I got the impression at my local episcopal church that gay people were welcome as long as they weren't too obvious about it. The older parishioners might feel threatened by gay public displays of affection, ie. holding hands, kissing. You're very welcome to worship and drop money in the plate; just keep your displays of affection private.
"Beloved let us tolerate one another. For tolerance is of God and everyone that tolerates is born of God and knows God. He that tolerates not, knows not God for God is tolerance." 1 John 4:7,8
