An invalid argument is a phrase that cannot be interpreted as an argument or not on the topic of gay marriage.

Example Input: b.) Even comparing or using in the same sentence Nazis, slavery, etc. with gay people and what they deal with is terribly, terribly disingenuous and offensive IMO.
Example Output: Valid

Example Input: Let the government decide this on a purely constitutional or legal basis (because that 's its function).
Example Output: Valid

Example Input: I can define evil acts by how they affect fellow living things, murdering another human being hinders society, therefore it is an evil act, and since your Bible condones the murder of innocent lives, I consider it an evil book.
Example Output:
Invalid
