"Gays can get 'married' civilly, but not in the Catholic Church."

Wholly irrelevant to gay civil marriage. Gay couples can give "total self gift, one for the other". If you say they can't, then you don't know any gay couples. You are going with your feelings, not reasons.

You are pushing the idea that people get married to have children. While that is a reason that some people get married, it is generally not the reason  people marry. You are also getting close to saying that heterosexual couples who are unable to procreate do not have proper marriages.

"You believe love is a feeling, not the willing sacrifice of one toward the other's good." 

Two problems: First, it is not what I believe, and nothing I have ever said would lead a easonable person to say it is. Second, if this is an argument against gay civil marriage, it assumes that gay couples cannot make "the willing sacrifice of one toward the other's good."

No, you have given us your feelings, and nothing else.
