In general, when somebody is advising you against discerning, untangling and questioning, chances are, you are being manipulated.
it's critical to stand with others, but it's dumb to hold back good things for a minority group all groups can get what they want, and ostracizing and exiling others because they don't care enough about all the other things some cabal of the organizers of some particular movement/protest is the exact opposite of accepting others. and yes, there are issues where the tolerance of intolerance can become a serious problem, but to find those it's surprisingly not enough to apply mob justice on the spot. aaaaand yes, there are those things where even that's okay (let's say someone starts to unfurl a nazi flag)
(and excuse me for my own rudimentary dumbing down.)
