Joe- “If someone merely was attracted to this sin without actually engaging in it, he wouldn’t be declaring to the world his attraction to the sin anymore than someone disposed to theft or adultery would march in a thieves or adulterers pride parade.”
I strongly dispute that. Today, it’s an identity thing. We all label ourselves and try to associate ourselves and identify ourselves with groups that support our experiences. LGBT is one of those identifiers, so even people who are not in gay relationships have ample reason to identify with the general grouping. In fact, I’d say kal vachomer in the frum community, as even for someone with no intention of sinning, it is much harder to be gay in a community which a) emphasizes the kinds of families that these people can never have and b) is automatically suspicious of them.
For the record, I would never go to this parade, though I know people who did this year specifically as a statement in response to last year’s tragic murder. But I still disagree with you on that bit.
