What do you mean how so?? A law restricts gay people from getting married, that’s your position. A law sets regulations around voting like voter ID. Those are regulations. Those are what conservatives promote. I understand you have reasons for them, but that doesn’t take away the fact that you are calling for state regulations over Liberty, individual rights and personal responsibility
Marriage and individual rights are two different things. Marriage rights never restricted anyone from getting married. Marriage use to have a distinct definition, it no longer does.
Voting laws protect against fraud, supposedly, If you are a citizen of this country who has no restrictions placed on yourself from crime, etc. you have a right to vote. Do you not think voter ID is a good idea? How about ID to board a plane, drive a car, buy alcohol?
