It's legal for an adult to drink a handle of vodka every night. Doesn't mean it's a good idea. It's legal for you to tell your neighbor you hate them. Doesn't mean it's a good idea.
This is disingenuous. Drinking vodka is not a constitutional right, it is just something that is not forbidden by law, so you are comparing 2 very different things. For any constitutional right people should be proud to show support and exercise it as much as possible, otherwise it is not a right, just a permission like drinking.
