You posted that the vaccinated are still getting covid 19. I agreed with you. How is that a strawman argument?
I then qualified that agreement by demonstrating that while the vaccinated are still getting covid, it is in much small numbers than the unvaccinated (like 95 to 5). Again, that is not a strawman argument. It directly addressed what you said.
A strawman is when you demolish a different argument than your opponent presented, because it is easier than demolishing your opponent's argument (just as it is easier to punch down a straw man than to knock out a real man).
I did not contradict your argument at all. Indeed, I agreed with it and added additional information.
By directly addressing your argument, I did not commit a strawman fallacy even if I had been disagreeing with your argument (which I did not see my argument as doing, indeed, the first few words are agreement).
Did you mean that the vaccinated are getting covid in the same percentages as the unvaccinated? If so, then my post may have disagreed with yours, but I did not read your post as making such a claim. Even if you were attempting to make such a claim, a post directly addressing that claim is not a strawman.
