Most of the people here are anonymous or pseudonymous. You may not know who is on the other end ? It is wise to respect every one's each other.
Respect must go both ways. If you don't respect the community, then you can't expect the community to respect you.
How would you feel if I came to your house and put my muddy shoes on your dinner table? That's how I see what you did here.
Every one deserves a respect, are you are aware that the forum does not welcome abusive language to a fellow user. Theirs so many ways to correct somebody you know that is on off point. You can message the person through inbox and explain things with person than insulting the person on public or you blacklist the person knowing that what ever the person's post you will not see it or come across to the post, insulting the person every time, it will demoralize the person ambition.
