One thing for sure is that you can not trust a Muslim.
It is their duty to lie cheat or steal from/to non- believers.
What this fellow say might or might not be true.
al-Taqiyya is a real tactic that is commonly used between Muslims and non-Muslims.
Not all Muslims are the same. Some are truthful, they are often hated by the Islamists and some are killed for it.
The Alevi’s are a group who are reliable. They are marginally Muslim and have a good reputation as far as truthful goes. There are other groups too.
I’ve found this varies a lot depending upon the country they are in.
I know a lot of good Kurds. In Syria the number of non Muslim Kurds is higher, than in Iraq, Iran and Turkey.
I wouldn’t put any thing past Erdogan doing....his history is one of supporting and funding Isis and other terrorist groups for years. He’s one ‘evil’ beast to say the least.
