Hmm… I think that most actual implementations of “hating the sin and loving the sinner” amount to hypocrisy; at least the ones I’ve seen personally, anyhow. I saw very little love from representatives of the Church in the lead-up to the approval of same-sex marriage here in Canada. The local archbishop even published an “open letter” in the country’s newspapers encouraging our lawmakers to invoke the notwithstanding clause.*
You cannot say Catholics are hypocrite to oppose same-sex marriage even asking laws enabling this to be reverse. This is exactly our stance. In our understanding, living this lifestyle instead of other choices are unhealthy for homosexuals. The Catholic stance supports the individuals to have opportunities to thrive in society, to be free, but not to have sexual unions with their own sex. You might ask, what “love” is there to the individual if they cannot choose their own path. If you do ask such, you do not understand Catholic teachings. This life on earth will pass away and then there is eternity in Heaven or in Hell. Choose Heaven. Secondly, there are alternative lifestyles then being in sexual unions. You can still have brotherly love, you can still love your parents and siblings. You can be a chaste person. You can live in a society in a chaste way.
These are options you can choose to commit to instead of giving into your lusts just like a straight guy can choose to do these things instead of having sex with women. The difference is that a straight person can have a single spouse, while a person that cannot enjoy heterosexual relationships cannot.
Think of it as a cross to bear, just like how a wealthy person is called to be generous, a gifted person is called to serve others with his gift. If you claim it is not the same, then think of a mentally crippled person
choosing to love themselves and be a source of happiness. This is a choose. I do not know if you can choose to love women, but you can choose not to have multiple partners for sure, you can choose even to be chaste, or you can choose to live in a way you want because only your own wishes matter to you and not anyone else even if it’s God.
