It may just be the language difference, but I get the idea from your posts that you do think that being gay is a sin. It is not. Talking about “allowing gays” to attend Mass puts homosexuals on a different level than heterosexuals. They are not. All people, heterosexual or homosexual, are sinners NOT because of our sexual orientation, but because of our behavior. All of us, if Catholic, are still obligated to attend Mass, confess our sins, and live our lives in accordance with Church teachings.
Edit: I just saw your other response that you posted while I was typing this. I am glad to hear that you do understand the difference. And, yes, I do believe it is the language issue.
