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.

The fact that it is impractical to offer the benefits of marriage across many people is really far more important than the inequality, since the inequality would only be helping some families while hurting no others.
Valid

Marriage evolved because of moral and religious grounds rather than a mere union approved by the state... To debase marriage just to accomodate base desires of gay couples in disguise if a right is simply stupid...
Valid

Hetero and homosexual couples should have equal protection under the law.
