We would like you to assess the QUALITY of each of the following argument (discussing Gay Marriage) and determine if the argument is Valid or Invalid. A valid argument is clearly interpretable and either expresses an argument, or a premise or a conclusion that can be used in an argument for the topic of gay marriage. An invalid argument is a phrase that cannot be interpreted as an argument or not on the topic of gay marriage.

And right now, as long as marriage laws deny marriage rights to same-sex couples, they are unconstitutional.
Valid

If you say you are going to prevent people from voting if they cannot read, and then ONLY apply that to blacks and NEVER to whites, the law is bound to fail 14th amendment testing.
Invalid

I never said they weren't discriminated against in history, that is certain and the way gays have been treated is sick.

Valid
