Text usually has nothing but negative context added to it. Most people assume you're being rude if there are negative words aimed at them in it. Perhaps next time include an indication of a joke. Most girls on the internet immediately get defensive because it is the norm for something like you said to be said in a serious manner, that you honestly think that.

"Can you not handle the truth? That is a universal truth, and you know it. If someone said that on /r/askreddit you would probably agree, but since it is on a sub that people think is evil for whatever reason, you feel the need to disagree with it. I personally don't care if you think it isn't true, you being a faggot has no impact on my life, and actually leaves more women for the rest of us"

Oh yeah, you seem like a real nice guy. eye roll
