Logical fallacy: Slippery Slope
LGBT involves expansion of marriage rights.
People marrying animals involves expansion of marriage rights.
Thus, LGBT legalized marriage will lead to people marrying animals.
Problem with this fallacy:
LGBT couples eligible for marriage equality are made up of consenting adults. Animals are unable to consent seeing as they lack sapience and thus cannot legally consent to anything. Animal marriage is therefore not equal to LGBT marriage.
