Dave,
Q. If people who have sex outside marriage are unrepentant are they damned
A. Yes

Of course they are not silly.

No religions and few countries allow same sex marriage.
Is that your only complaint against the Catholic Church on this?
If so we do not disagree.

Jim, this is the official, current view on homosexuality from the catholic Church,
" being homosexual is not wrong or sinful in itself. But just as it is objectively wrong for unmarried heterosexuals to engage in sex, so too are homosexual acts considered to be wrong."

No discrimination, except the marriage thing which is still almost universal.
Why single out Catholicism?
