Excepting the “liberal” insertion, this is such a truism, that with it in, it is quite possibly the dumbest thing I have ever heard, and if you think it is ironic that I say so in this thread, then you’re probably not even paying attention.
Firstly, that when we think we are right, it generally means we think others are wrong. That is simply a consequence of the binary nature of truth. At best truth has three states, which are true, false, and undetermined. At best. But generally, once one has resigned oneself to correctness, it quite surely means other people are at the very least misinformed, classical causes of which are being simple or uneducated, though other less pleasant possibilites can present themselves.
Secondly, “know what’s best for everyone” is part and parcel of national politics. We’re deciding law here, not making suggestions. The contrary of “knowing what’s best for everyone” is still “knowing what’s best for everyone”. You do not get to escape that very real dichotomy: either a suggested law is best for everyone, or not passing that law is best for everyone. Again, we may attempt to hedge our bets by being undecided, but there is no way to have an undecided law: it either passes, or doesn’t, and so the facts of the matter side with one camp or the other, regardless of any inherent correctness.
Finally, the very thought of telling liberals what’s wrong with them is that they point out what’s best for everyone has the rather implicit judgment that what’s best for them is not doing that, creating some bizarre circular hypocrisy that can only be mustered in threads like this.
It is, though, more simple than that. So long as we survive, we will change, and so long as there is change, there is resistance to change, which is, definitionally, conservativism.
Reminds me of a coworker. He told my friend, “See, now that you own a house, you’re going to become a conservative.” Must have known what was best for him.
Of course, so far, he’s been wrong.
