Most libertarians, like myself, don't believe in the climate crisis. Sorry. And no amount of yelling about it is going to make me change my mind. You'll just have to be satisfied with being in the majority on this issue. Not everyone is going to agree.

Racism: A true libertarian abhors racism. All men are created equal.

Covid: I think it is becoming clear a libertarian solution of voluntary vaccination and protecting the vulnerable would have worked out better than the authoritarian solution of locking down the country with all the ills that created. Sweden didn't do these things and they got through Covid in pretty good shape.

inequality: If you mean financial inequality, no, libertarians don't think much of the problem. But I'd point out that the super rich got where they are by manipulating the government. If they could be prevented from doing that, economic outcomes would be much more even.
