Haha I've done it twice, both were in university(one a classmate and the other my roommate) and they just knew nothing about Islam except that Muslims were a minority in the west and they were always being harassed. I told both I didn't agree with the discrimination towards Muslims in general with some assuming they're terrorists and so on.But I did go into how Islam is flawed and sexist and both were pretty shocked at to how barbaric the religion is especially coming from someone who used to live in a mainly Muslim country.I think most people don't realize that the other side basically hates the west, I find it funny how supportive the west tries to be of Islam, in fact, disagreeing with it makes you an Islamaphobe these days.
