Filter bubbles are real. If you spend your time watching (low quality) videos with a bent (anti-feminist/transgender, e.g.) you begin to believe that is the majority discourse.

Its similar to homophobia - a small (tiny) portion of the population expresses "nominal" preference towards homosexuality, however, there is an outsized fear among those who feel threatened by the concept...

Well your argument holds all the same should you replace "anti-" with "pro-" etc.
