How would you approach Islam or... are we ashamed to?

First person:
"Invite (all) to the Way of thy Lord with wisdom and beautiful preaching; and argue with them in ways that are best and most gracious: for thy Lord knoweth best, who have strayed from His Path, and who receive guidance." (Yusuf Ali translation) Qur'an, Sura An-Nahl 16:125.

Understandably, the need for da'wah today is essential to all of muslims throughout the world, due to the tricks of the media abusing and deceiving us to those who are confused, disoriented, and oblivious about Islam. In addition, in effect of the misguidance of the amiss media, not only that it misguides the nonmuslims but as well as some of our discombobulated muslims and most importantly, the misbehavior of the muslim youths, who are the faces of our future. They do not realize the slaughter of innocent human being, is clearly condemned by Islam. Being how, this is where the da'wah for Muslims are absolutely essential in order to bring forth the truth of Islam and to correct the confounding. Unfortunately, because of all the politics about us today, some Muslims are ashamed to make Da'wah.

Second person:
Yes, a youtube speech by Al-Qardhawi also stated the same thing, in the context of invading europe and america through an army of da'wah. He has postulated, if I'm not mistaken, that rather than bombing america to ashes, he pleaded all Muslims to become an army of da'wah, converting america and european countries to become nations of Islam.

But in some instances where it is almost impossible to convert or to revert, al-Qardhawi has stated that we do not preach. Such an example would be the Sunni and the Syia. He urged that both sides to not preach the other about their stand. It's rather unfortunate, but more harm than good would come from the clashes of these 2 factions, even in preaching and spreading words of faith.

In my opinion, there are a number of ways we can participate in da'wah. Even if we cannot fluently conversate, we can actually participate.

1. Politics:
i. If we are already leaders in certain establishments, the da'wah would be mainly to our staffs. If we ourselves can't do it, we either learn or find someone who can.
ii. If we lead something bigger than an establishment, like a state, a country, or even a district. This makes da'wah an easier job. Leaders of this level should organize campaigns and informative sessions to educate the people. Collectively acts that support the education of Muslims should be strongly reinforce, including building of religious schools, enforcement of syariah law according to the Quran, and to put a tight leash on the very cause of social problems: entertainment of hedonistic value.
iii. If we feel that the political party which represents the party does not support da'wah, topple them down from the throne politically, through votes.

2. Economy:
i. If we can't fight the fight, at least support it. If Muslims can grasp economy in the balls, we are powerful in almost every fund-dependent aspects which retads da'wah: solving problems of poverty, education and expansion of business and trade.
ii. Never neglect zakat. This is the start of an Islamic economical cycle for everyone.
iii. Never sell lands, houses or shop lots to kafir. A specific way to ensure that the kafirs will not come a step closer to depriving us of our own economical ground. Never forget that the lands of Palestine were lost because they were first sold to the jews. Now, we're having a hard time getting it back, and due to this, we are condemned to re-take Israel, since thay claim we have sold lands there first.

3. Social:
i. Education is the "reincarnation" of jihad in every youth. Ensure our children goes to religious school. Even if they someday go to a higher education where religion teaching is sparse or none, make sure they practise or re-learn slowly about Islam.
ii. Restrict entertainment as this is the actual cause Muslims would rather watch American Idol compared to performing the Solat or reciting the Quran.
iii. Join or support groups of da'wah, when you know they are not going astray from Islam. Such example would be Tabligh, a very strong group established in India-Pakistan by Maulanas there, which go from door to door just to spread words of faith and encourage Muslims to go to the mosque. Another would be the subversive group Jabal Nur (mountain of light) / Brotherhood of the Moon. This anti-christianization movement established in Malaysia is starting an underground movement to counter christianization and Murtad, strengthening Muslims from the roots, and adding their numbers by conversion of non-muslims through education and good display of manners.
iv. I can't comment on more radical movements such as Al-Qaeda or Jamaah Islamiyya,or Abu Sayyaf, since I never met them and never actually conversate with them. We can't speak about people when we vaguely know why did they perform bombings and Jihad in an uncommon manner.
