It's amazing, the amount of selective reading going on from both Scuddie and Trashman is unbelievable, you don't know what it is or what causes it, but it scares you, and THAT is why Gay Pride exists.
As has been pointed out, and once again, simply saying 'Bah... that's not the same thing' doesn't change a word of it, they are genetically, and evolutionarily errors, as I said in my first post, but you both chose to ignore it, it's not along the same lines as Arms or Lungs, but that doesn't make it any the less natural, and does not always mean it needs 'curing'.
Once again though, it's better to zero in on homosexuals because they are...well.. homosexuals, and everyone knows we should pick on them because...well.. they have sex with other men. It's that which it boils down do, and that which they've been persecuted with for years. That's why, when Pride was finally formed they took it to extremes.
As has been mentioned before, there are a great deal of traits that are considered 'errors' and a great deal of prejudice against them, stop whining and they'll stop winding you up, trust me, you get offended only at Gay Pride festivals, you only have to read this thread to see what way attitudes go for the rest of the year.
If you dislike having Gay Pride rubbed in your face, then fine, but this whole 'Homosexuality is a disease' bull**** is generalisation and vague speculation that even Scientists aren't certain of how or why it exists, but you've already decided that it's something 'different' from say having a Birth Mark.
