I was delighted with the LGB Alliance was formed and gladly support them with a monthly direct debit. In fact I doubled the monthly sum a while back, inspired by trolls who turned up here to warn us of the dreadful peril of supporting an organisation formed to protect the rights of same sex oriented people.
