There's a difference between being honest and being insulting. And because you may have read the post differently than another poster does not make you the authority on someone's ability to comprehend logic.i have a need to speak the truth.You just have that need to insult people.
what is clear is that you don't seem to understand basic logic because his post makes perfect sense.
So far you've said you respond to people in person as you do here. So it would seem that if your boss, parents, spouse, colleagues has a difference of opinion or a different understanding it is ok to call them stupid and be demeaning. In my world, that would get me fired, single, and friendless.
Everyone should be honest. Nobody should be rude
