It's troublesome that because people are sarcastic and caustic by nature, they assume anytime anyone else types properly, and tries to address them in a sincere way, they are being condescending. I have to be very clear in my English, as it is my fourth language, and I like to avoid misunderstanding. If anything, this ought to reflect my sincerity even more, and show that I am earnestly expressing how I feel without trying to put you beneath me.
If you want to have an informal discussion with me, expect a multitude of misunderstandings, and a modicum of Basque slang involved.
I am sorry you feel that way, and sorry you automatically assumed the worst of someone.
