Have you noticed on Youtube that you're merely agreeing with a video or just make a comment and people starting to argue with you about your comment because they say it's wrong and/or say hateful things about you, your race or whatever? Well, I have experienced it sometimes. Well, I decided to say my last piece and then ignore the message, because I don't find it necessary to repeat an argument with that women/man/boy/girl, I simply won't be bothered with it through my email again!
