Most Christian denominations conduct at least some discrimination against gays...many still bar 'practicing' gays from the clergy or high office, Catholicism still forbids 'practicing' gays from communion (as well as high church officials continuously making hateful anti-gay remarks), and few churches offer the Sacriment of Marriage to same sex couples.
Any denomination that operates in any of these or similar ways is guilty of discrimination, and of assigning second-class citizenship to gays. This is a sometimes subtle, but nonetheless real, instance of systematic denigration and humiliation of an abritrary group of people based on cherry-picking of certain Biblical passages.
Virtually all educated people in the world know that being gay or straight is not a choice, but rather a condition of birth.
Straight Christian parents cannot force their children to be straight.
Therefore, Christian parents can give birth to gay children.
If you are a Christian, how will you feel when your kid starts to come out, knowing that for years you have been supporting an organization that denigrates and humiliates gay people?
How will you feel knowing that your kid has gone or will go to religious instruction that promotes an institution that denigrates and humiliates gay people?
How about if isn't your own kid, but your friend's kid or a niece of nephew?
Do you ever wonder why so many of the institutions claiming to be god's representatives here on earth have such a long history of picking out certain groups, like gay people, brown people, Jews, Muslims, etc. to denigrate or humiliate?
Genuinely interested in how liberal Christians respond to this.
