So it sounds like we are on a similar page. We are not more likely to ask for the arrest of a homosexual couple engaged in a deep kiss than a heterosexual couple. But, it is more destructive to the culture to allow a homosexual couple to kiss in public than a heterosexual couple. The heterosexual couple is demonstrating poor taste. The homosexual couple is demonstrating perversity that we don't ever want to mistake for normal.
Shalom.
I notice that you only describe homosexual kiss as deep, not the hetero kiss.
Hmmmmmmm... That's odd and creepy.
If so, what is your definition of public? It's a very serious question, because I think someone suggesting punishment for public acts should make a distinction between public and private. Does a private act only occur when the two committing it are present? Could there be others around who consent to/agree with the act in question?
