Maybe it does have that tone. But this is a reality. I'm including myself in that too. If I say or type something online then I expect there is a likelyhood someone could challenge me on it. It's the gamble we take when offering an opinion to a conversation, that we're heard and acknowledged. If you want feedback from our opinions then its either all kinds of feedback or nothing at all.
I'm not saying the situation is right or correct. If we take away peoples personal responsibility for the things they say and do, then that will create even more extreme views in society, with threats to kill people, because they would know there is no come back.
It's like if someone says something racist, don't you think they should get feedback on that?
I'm for free speech and would only consider it a problem if someone is saying or writing directly to physically injure or issuing death threats against someone. Any other comment I'm ok with. I think for humans its not possible that we all agree with each other. I think its nature that we'll argue. The only way lunatics who try to become violent will be dissuaded is if all the reasonable people from all sides start condemning it, even if the person is doing in the name of an opinion they support.
