I don't dispute the logic of people wanting to change an unjust status quo, I'm just trying to see the bigger picture, that the side supporting the status quo is worried that certain changes would cause society to degrade or become unstable.

There probably are cases where making people feel uncomfortable does lead to them changing their minds and accepting the position of the person making them uncomfortable, but I think the assumption should be that supporters of the status quo will just become more entrenched if they see people trying to make them uncomfortable, just as those working against injustice can become more committed to their cause when they face opposition.

There is a long history of progressive social movements we can look back on for evidence.

Humans, on the whole, succumb to pressure to conform. And rightly so, the alternative is antisocial; sociopathy.
