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

SOLUTION: Valid

PROBLEM: The difference with homosexuality is that most people don't want to break those "rules", and so it's easy for the majority to say that they should remain in place.

SOLUTION: Valid

PROBLEM: Well, if we decide to make incest not taboo, we will have a different discussion, one that doesn't have a bearing on gay marriage or inter-racial marriage.

SOLUTION:
Valid
