Saint Valentine is the name of several Catholic martyred saints of ancient Rome.
His day is about naked baby archers shooting love into people's butts.
Love in people's butts naturally leads to courtship.
Courtship leads to marriage.
Marriage leads to sex. (See citation #1)
Sex leads to babies. (See citation #2)
And babies are made ONLY by heterosexuals. (See citation #3)
So...
...letting Gays have sugary, pink "You Complete Me" candies is the slippery slope that leads to the debasement of marriage and the end of the kind of America that the Founders envisioned... specifically where Black people pick crops that turn into undergarments and Women are forced to have babies unless they can prove that they were really and truly and honestly raped.
To this end, The All Loving God has commanded the Catholic Bishops to demand that Catholic checkers at Walmarts be allowed to ask pointed questions (color scheme questions for men/obscure softball infield fly rules questions for women) to determine the sexual orientation of any individual trying to purchase flowers, cards, or edible chocolate panties during the month of February. (See citation #4)
Anyone failing the above tests will not be allowed to purchase said items and will be told that they are now and have aways been... somehow less than normal.
Anyone demanding proof God's Intents need only look in the bible right before the passage where it tells us...
No one whose testicles are crushed or whose male organ is cut off shall enter the assembly of the Lord.
...and right before the part where it tells us...
If two men, a man and his countryman, are struggling together, and the wife of one comes near to deliver her husband from the hand of the one who is striking him, and puts out her hand and seizes his genitals, then you shall cut off her hand; you shall not show pity.
Thank you,
