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: In either case, it is a weak argument for the RC being anti-gay, since homosexual sex is just one of a hundred or so "risk factors" that disqualify one from donation.

SOLUTION: Valid

PROBLEM: But opposition to allowing another person the same civil rights you enjoy is, as I agree with Jaxian, MORALLY WRONG.

SOLUTION: Valid

PROBLEM: By denying homosexuals the right to marry you are creating a second class of people; you are discriminating against them by saying that they are not worthy of long-term, legally recognised relationships, yet heterosexuals are.

SOLUTION:
Valid
