A whole slew of the birthday cards for young heterosexual men and women on display at a card shop near you are not suitable for children's eyes, between the nearly naked swimsuit models and the mildly amusing explicit sexual innuendo.
So why should I worry about a wedding card with two tuxedos on it?
Because homosexuality is deviant, dangerous, disgusting behavior that must be tolerated but should not be celebrated. This is the mainstreaming of the aberrant and naturalizing of the unnatural.
This is a fight of decency and god vs indecency and evil.
