Why do you assume I don't take it serious?
People spew this word 'toxic' as general fact, while it is highly subjective opinion that varies from person to person. I personally experienced behaviour I considered over the line just once, rest of the 'toxic' behaviour I seen was just occasional arguing, insults and tantrums.
Do I get upset about it? Yes, but it doesn't stop me from playing the game. However there are some oversensitive people telling others to "stfu dont tell me what to do" after you just asked them to take a camp (When they have a good Hero for it).
I do believe people make this a bigger problem than it really is. If you disagree and think this is a huge problem, fine.
