Acceptance comes through dialogue, and mutual understanding.
Sadly, there's a lot of "open minded people" who are pretty close minded to openly entertain a viewpoint that isn't their own, let alone be able to look in the mirror.
It can be easier (and lazier) to trivialize, dismiss, degrade the viewpoints of others, or be a crybully, rather than have a sincere look at yourself in a conversation.
Add into the mix reasonable themes of fragility, privilege that one group has been raised with (not entirely their choosing but a responsibility to work on), and in another experience at the expense of others, another group having an unfair go for a number of fair reasons.
The reality is bias exists. The best candidate does not win if the decision makers are not of the best and of the most open temperament.
I read somewhere that some of this may be a majority having the experience of a minority for once - and maybe that can help drive a better conversation and mutual understanding.
One thing is for sure, being quiet won't work, and freedom of speech without being thoughtful with your words won't help either.
