To me Islamic scholars are some of the most intellectully brightest minds out there. They spend decades studying the book of God and God's message to mankind and they spend their lives guiding and advising people and not compromising their beliefs even for all the wealth and power of the world. They treat the disease of the heart and mind and deals with social and emotional issues of human beings. U can google Ibn taymiyah, Ahmed Ibn hanbal, imam nawawi, Abu hanifa, imam shafi, imam Bukhari etc etc. They were some amazing scholars who by the will and permission of God changed the course of history.
As for your questions:
1) your first question is a strawmen argument. When did I say EU should be like BD? Are u out of your mind? That was very intellectually disingenuous of you. BD is a 3rd rate secular shithole and not a good example to follow. Infact it's BD which follows Europe. It still follows British common laws that allows the president to pardon convicted rapists and murderers just Bcs they are secular ruling party members.
2) that's what your society has become over the last 200 years. If u need vulgar satire and making fun of dead children to relieve your stress then their is something seriously wrong with your society , IMO? But then again that's just me , a fundementalist Muslim. U enlightened liberals may see something funny in other people's agony in calamities that my fundementalist eyes can't see.
3) 99.99% don't even know who Renzi is. 95% don't even know Obama or Hillary. But assuming your hypothetical strawmen scenario , most won't even comprehend making jokes like "Renzi fucking goats". Some may make normal jokes but if some egalitarian liberals influenced by western liberalism do make such vulgar jokes he won't find any takers here. In fact he may be publicly rebuked and condemned for having such a sick mind.
Btw erdogan didn't ask for that comedian's blood. He asked Germany to follow due process of German law. I don't see why anyone including u should be hysteric abt that.
