IMPORTANT: “Criticism” that starts with “All *…” or is obviously insulting, or defaming beyond verified facts is excluded.
You might be thinking “no shit, Sherlock”, but it is really common that legitimate criticism is dismissed as anti-* or *-phobic, or because of political or religious ideology.
I disagree with generalizing. Usually the most controversial takes are the loudest and draw the most engagement. A lot of peoples intent is to deliberately ragebait. Also it depends on the country they live in. For example, I have huge respect for feminists in countries that may prosecute them with extreme and inhuman measures.
Edit: Thinking about this more, I have also made the observation that legitimate criticism against a woman is much more commonly met with severe, often undeserved backlash.
