So, you equate polygamy to bestiality and feel that it is a step beyond what should be acceptable as normative behaviour, I take it you don't support either then.
Who are you to decide how many people can be in love in a state recognised relationship?
How does someone loving more than one person affect your life?
Casual sex with multiple partners is ok but not marriage?
I won't respond to your bestiality comment but I'd be happy for you to expound on it, since you brought it up.
I don't hate gay people, they don't frighten me or cause me any harm whatsoever.
Unlike your response, which is typical of anyone who refuses to see contrary opinion and defaults to labels and -isms to stifle debate and accuse hatred where none exists.
