"What is it you feel gives you the right to tell others Shut Up!? "
When that person either posts or answers with an arrogance that the person knows everything and the other person does not. Or, when every other answer to a post refers him or her to the persons system. It gives me the feeling like that person is saying that theirs is right VS all the rest of us. Another thing is when the poster has to post their conspiracy theories or reminds us that they love our President which brings politics into it. .
As for myself, I am guilty of getting involved in the Political atmosphere which gets me hyped up and then someone reports my post to a moderator. Then I get more annoyed and have to keep it all in until the next time at which time I unload on someone. Not healthy for me or any of us. I will be the first to admit that I am extra jumpy right now due to the Covid-19 problem, but that is no excuse when I screw up and I should try harder. I will try harder, how about the rest of us?
