Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
It is usually just as religiously important to same-sex couples to be married as it is for opposite-sex couples, and no one should be able to tell those people that the government cannot recognize their relationship.
Solution: Valid
Reason: It is a clear argument that supports gay marriage by saying it is as religiously important as opposite-sex marriage.

Now, solve this instance: Significantly, the group emphasized, Quidachay denied San Francisco's request to stop the case in light of the city's lawsuit filed Thursday against CCF and Liberty Counsel, claiming the "equal protection clause" requires homosexual "marriage."
Student:
Valid
