Oh for God's sake put your Captain Spellcheck tights in the closest. Of all the petty 4 year old comments.You can't even spell the concept, much less articulate an understanding of discrimination.
You keep repeating like a parrot that I don't understand the word discrimination.
Let's look at it
treatment or consideration of, or making a distinction in favor of or against, a person or thing based on the group, class, or category to which that person or thing belongs rather than on individual merit: racial and religious intolerance and discrimination.
Now, explain in your words how you are not discriminating against someone who believes what NAMBLA believes and you exclude them from your group.
For once in your life answer the question.
