I think that harshness of laws is a different issue. The thing seems to be that legislators do not want to be seen as soft on crime, so they tend to outdo one another with stiffer and stiffer penalties, which of course are not fairly applied. The rich sometimes get away with murder, the poor might go to jail for littering. Whether or not some particular activity should be legal or illegal is a debatable topic and there is no end to the debate. But what something is described as is sometimes turned on its head. In theory, conservatives would want conservative gun laws, not liberal gun laws.
These days, people have divided themselves up into groups with different standards, traditions, morals and conventions. Essentially, it boils down to "us" and "them." So people want laws that represent their own group's standards, etc., which seems natural enough, no matter what their own group actually does in real life, which might be contrary to their dearly held moral standards if it appears to be convenient or necessary at the moment. That is sort of a definition of hypocrisy. But I'm sure none of us are guilty of that. My standards aren't particularly high and are easy enough to conform to.
