Silly annoyance

I know it shouldn't irritate me but i can't stand when people use imo. Idk it feels passive aggressive even though it shouldn't do; Same with "its just my opinion" and anything along those lines when its uses to say nobody can disagree. Like an opinion isn't an unchangeable view and something being an opinion doesn't make it morally correct- opinions can be wrong and harmful and we shouldn't just waterdown our world views to "opinions". Racism, homophobia or any kind of bullying/ oppression is caused because of people having dumb opinions on how people should look or act; opinions aren't inconsequential, they can cause harm and it irritates me that people don't understand that.
