You've got to come to terms with the fact that everyone perceives things differently. No matter how much sense you think you're making, in someone else's eyes they're making just as much sense. You may eventually come upon someone who can admit when they're wrong if you have sufficient evidence to support your claim, but that's a rarity here. People seem very content with ignoring hard facts because it doesn't suit their agenda. It's not worth wasting time posting back and forth with individuals such as these, as you will only waste your time and the state in conclusion will be no different from when you began.
well this type of person is sometimes easy to find, they tend to be coarse, act as if you just insulted their mother, even better, they begin to use words like sexist, homophobe and misogynist to attack you and make you shut up, and try to win the argument.
Sorry bad english.
