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.

I have found that the majority of people who claim others use fallacies haven't the faintess clue about how they work.
Invalid

Valid

That statistic could mean that marriage lowers promiscuity, but it could also very well mean that it is only the non-promiscuous people who get married.
