It doesn't excuse his reactions either, which is my main issue really here.
Just because many are out of line, doesn't mean the OP should be excused for ignoring those who do want to discuss it further with him too.
The OP chooses to give low effort responses to those they felt offended by, rather than having a proper discussion on the matter, when he's the one asking for advice.
Could just ignore those with low effort, which isn't that hard to be honest.
I just had to do it myself earlier, and still had some good discussions with others in the thread that were more genuine.
I think it's fair that you want to call out the ones out of line, but you're starting to defend the OP more than the OP has put effort in defending himself, and that to me just feels awkward.
Maybe if the OP is actually putting forth more of an effort, and defending himself, and actually responding to people who want to have a conversation, then I'd say it'd be a more valid approach, but as it stands, if the OP doesn't even putting in that effort, now it just feels like you're speaking for him, rather than letting him speak, which is a bit problematic in itself anyways if we're talking about having a proper discussion on the topic.
