I can be totally accepting of how they choose to live their lives and still find the fact that they are attracted to one another sexually repulsive and gross. I can and do find a profoundly overweight hetero couple french kissing gross, too, but I have no desire to ban or outlaw such relationships. Now if I did, for some reason, then I'd be unreasonable in my attitude towards the actions of two consenting (though very overweight) adults. Live and let live, I say...but I can still feel that way and find two dudes sucking face to be nauseating.
