I don't see why people have drawn the line. My mind keeps attacks and jokes on a flat surface without walls. If I am attacked (and I was), then I will attack you back in a way I know that will piss you off. Deadpool was transphobic, so what would be the best retort? Oh, he confessed to me of course!
And I ran with it.
If you are on good terms with me or neutral terms, I am the nicest person. I will listen to your problems, give you genuine advice, and Hell, in the case of one poster on here, I will look up services that will help you get over your problems.
I am really like a scale. We can be in balance, or you are on the up or down side of the scale. I can be overly the sweetest, nicest person, or I can be a very evil, vile person. I prefer the be the former, but people like Deadpool bring out my bad side. He engaged it and the scale on his side was too heavy.
Is ruining your credibility by faking a PM worth getting back at him?
Have you heard of the saying "Cutting off your nose to spite your face"?
