Sodomy, immoral marriage, sexual relations outside of marriage, homosexual culture, intolerance for those who disagree with homosexuality, government using immoral marriage to weaken the power of the Church of England and ruin the British governmental system. Total acceptance that homosexuality isn't a choice, rather than trying to help those people who become homosexuals because of abuse. So lots of things.
Of course this isn't a very important issue for most Protestants, we don't really care. The major issues for us are the break down the marriage as an institution between one man and one women for the raising of children. We also care far more about abortion.
