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.

As this gap broadens, people have a much larger range over which they might want to start a family - this results in people unwisely getting married too early in life, or putting off marriage for too long.
Invalid

Stop using the "sanctity of marriage" as an excuse not to give equal rights.
Valid

Just because a religion proclaims a marriage is to be defined a certain way does not mean the government must conform to the wishes of the religious definition, quite the contrary.
