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: Also, marriage is not just a religious institution (especially to those who choose to marry, who are not religious), and the common law requires no particular ceremony to validate the celebration of marriage.

SOLUTION: Valid

PROBLEM: It could only be those people who are uncertain of their sexuality right now; it could only be those people who might suspect themselves of being homosexual today, but deny it because of society's lack of acceptance.

SOLUTION: Invalid

PROBLEM: discrimination against gay marriage is based solely on religious beliefs and amounts to establishment of religion

SOLUTION:
Valid
