Does this mean that murder and stealing would be considered moral since they don’t cause a similar paradox? Everyone constantly stealing from one another does not create a contradiction (just a rapid movement of property) and everyone killing one another just leaves everyone dead, but the action is still universalized once.
The assertion of contradiction was basically Kant's argument, but you're right that it's a weak one.
Kant's argument was that if everybody murdered then we'd all get murdered up and wouldn't be able to carry on murdering in practice. If everybody stole, then there would be no property so nobody would really be "stealing" -- these are sort of true in practice.
But of course, that doesn't mean that a society without property would be impossible by any means; simply contradicting the viability of a concept does not prove that concept is actually essential. Maybe we just
don't need the concept of property at all, or could do with a radically different one. So, you could go around taking whatever you wanted without being morally in the wrong as long as you didn't act on the pretenses of holding any regard for the concept of property.
A murdered society would probably be impossible (since once murdered it's gone and can't do the thing anymore), so he may have a stronger argument with that extreme if you take his categorical imperative seriously. But it's also pretty easy to differentiate different categories of people and just murder them without murdering your own category and avoid the issue (e.g. murdering children born on odd days).
I'll let
@DarlBundren answer #2 because I don't really know the context.

He thinks he does, but he doesn't. Just these assertions of contradictions. Kind of like Isaac (Ask Yourself) actually... except Kant made the mistake over 200 years ago while VERY well educated on philosophy and was breaking new ground. Isaac is just repeating the mistakes long since put behind us by any serious philosopher, he's doing it not just in total ignorance but while lazily strawmanming other philosophical positions, and much more clumsily (relying on ambiguity to hide his mistakes rather than eloquently arguing his claims with precision). Also, Kant made real contributions to philosophy beyond his blunders with deontology.

Avoiding his "contradictions".

For example, it is rational for someone with a desire to be good to act in accordance to morality, but I would never describe acting morally as acting rationally in and of itself.
That's a question of binding force to morality.
It may or may not be true that we are rationally compelled to be moral.
If the paradox of hedonism is some essential property of mind, then we may be. But that's nothing like what Kant argued.
