It’s not because we hate them for their religion (for the saner part of Europeans it’s the same bullshit as Christianity)
Yes, I am firmly convinced that religion (and ideology) is used as a pretext for suppresssing people. One of Iran’s major partner countries is China, for example, but Iran says nothing about Beijing’s oppression of the Muslim Uyghur minority in China. They don’t care.
It’s all about power, and we see similar things all around the globe across all cultures and ages, including here in Europe.
