Extremism in any form is the biggest threat to peace in the world. Like google Christian terror groups in Africa, they are terrorizing people there, then there was Breivik a few years ago who was militant right wing extremism, then obviously you have the most recent Islamic extremism. THey are all bad, and anybody should fight against extreme views, them views generally include generalisations. WHich is the biggest issue that most people have with the label 'Islamic' being interchangeable with terrorist because it simply is not true. Are there muslims who are extremists, of course, but are there muslims who arent extremist, of course there are them too. And if you want to combat the PC brigade, and the SJWs and anybody else who you feel is some bleeding heart weakling, start there with getting facts, actual facts, not just 'IS are Muslim, therefore Muslims are all terrorist, because with a 2 minute google you can find Christian terror groups, does that make all Christians terrorists, of course not. And as for violence littered through the Qur'an of course there is, but is there violence littered throughout the Bible and the Torah, of course there is, so that doesn't justify it. The best argument you will ever have is with facts and figures, and dropping generalisations, despite them being easier for the majority of people to understand, because nobody likes stats, or facts, but ultimately ignoring them renders you simply wrong on all counts, in a debate where your voice may actually be worth something, and you could do some good, if you just researched what you were talking about and presented cold, hard facts, and not generalisations that make the headlines in Tabloid newspapers.
