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: But I can think of no reason for creating a separate category of civil unions for same-sex couples other than animus against gay people and a desire to treat gay people as less-than-equal citizens.

SOLUTION: Valid

PROBLEM: It is not unjust to oppose granting to homosexual couples benefits that in justice should belong to marriage alone.

SOLUTION: Valid

PROBLEM: Nobody is asking you to be gay, marry a man, or even like gay people.

SOLUTION:
Valid
