Looks like the great firewall worked well for you. Painting an entire ethnicity as terrorists who slash away randomly at people is exactly the kind of propaganda it serves. Israel does the same for Palestinians. Yes, terrorism exists and should be supressed, but you can’t de-humanize entire populations based on that.

Picture yourself being jailed, taken away from your family, forced to learn another language and change your customs because “people who look like you can be dangerous”.
