Peace be with you Jon,
Well illegal in a moral sense yes to both. As for the the difference between practicing the act or just being of the the preference, that is a difficult question for me to answer. I refer to Christ words on sinful thought being just a sinful as the commission of the thought. So I guess yes again. I need to read more on that but I believe it comes down to that issue.
I can’t see how thing about homosexual thoughts are any less sinful the thinking about murdering another.
