However, when someone online shares an opinion and it feels like they might be intolerant and you jump to the conclusion that they are intolerant and you launch into a tirade at them, this is not nice behavior. You didn’t check if they have the opinion you think they have, and that’s simply not nice to someone which you don’t know.
Very much this. Just because someone asked a question, does not automatically mean they are JAQing off. And I see people immediately jumping to that conclusion upon any questions being asked about sensitive topics.
