If you are Catholic, Specific forms of birth control are forbidden by your faith. That makes this a religious issue. If you aren't, you have to decide whether Ru-486 (the morning after pill) and other after conception forms of "birth control" are murder or not. Most of us accept that abortion is murder, regardless of what trimester is involved.
If you are Christian, how do you fund murder and remain faithful?
"Suffer the children to come unto me."
It IS a religious issue, not a question of buying condoms.
