Actually, your argument is just a non argument. "This policy should not be enacted because the people who want to enact it are hypocritical."
So hypocrisy makes for bad law now? Nah. Who cares.
Besides, framing an argument in order to lead your opponents into making a potentially hypocritical argument (half, if not most of the people in this thread didn't even fall for the trap), just shows that you're very insecure about your argument to begin with. Like I said, if you were legit, you would have made a thread titled "Should Gay Marriage Be Legal" with a list of arguments, one of them being about things like dwarfism. But in order to avoid having to make a good argument, you tried to rely on this deceptive strategy, which was only marginally effective in accomplishing what you wanted it to. Three or more people plainly said they didn't care about incest, some people didn't take a stance, etc.
Congratulations, you illuminated the possibility of hypocrisy. Unfortunately, it doesn't invalidate the passage of equal rights to gay people.
Classic slim thread
