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: Mosy who do not want it to be allowed just dont like homosexuality all together, and therefore the opposing side tends to be prejudice.

SOLUTION: Valid

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: The issue of same-sex marriage will determine whether marriage is about family or sexual preference, for we either give it to all families or all people of a specific sexual preference.

SOLUTION:
Valid
