No, there's an important difference between disagreeing with someone and harassing someone. I can disagree with you and still be civil, as I'm doing now. But some small-minded people go out and look for members of a certain group, whom they then harass: it might be women, Black people, Jews or trans people, for example. That (and not constructive differences of opinion) is what most people here want to stop.
Differences of opinion are valuable: they're how we learn. Harassment is just destructive.
