I don't see the argument why any of this is communism, bur rather what Republicans are trying to make you belief what is communism.
They have set education standards so low, that many can not do simple core subject aspects.
Nothing to do with communism or any political belief. Also partially Republican caused. Low education standards are a major issue as it stiffles critical thinking. I belief this is a structural problem in America with no party truly set on improving it in practice.
They want free education, health care, etc for all, without saying where that money will come from (taxes)
That's socialism, not communism.
they don't tax the rich sufficiently, and they are never going to do that.
Communism would tax the rich A LOT. E.g. Warren's wealth tax should be considered a clearly socialist proposal. Actual communism would simply take away ALL money of the rich and distribute it evenly (in theory) - basically, it goes to the state.
They have attempted to take away some very rights.
Which has nothing to do with communism, which is an economic doctrine.
Additionally, so called "acquired rights" could be taken away if there is good reason for it.
Ridiculous example: would you want free speech if producing any audio would summon a swarm of killer wasps that would instantly kill your neighbour? In such case, a government should restrict the speech of citizens, or at the very least give it a different meaning (i.e. online). Because by not doing that, they would essentially allow murder and you'd live in an anarchy.
But, obviously the benefits of taking away a right should outweigh the harm. This isn't always clear-cut, hence the debate around covid (There is no clear answer to the question: "how much "right" do you want to take away to save 1 life?"). Democrats will be more focused on the "saving lives" part, while Republicans will be more focused on the "keeping rights" part. There is no best answer on which one is best, although the approach of the current government was pretty bad unless you prefer a bit less economic loss over hundred thousand deaths which is arguably evil.
They appeal mostly to the rich and lower class.
Definitely not communist which does not appeal to the rich. Communist doctrine takes away all wealth of the rich.
The government assistance programs apply to the poor, which means they are now dependent on the government.
They key to a succesful communist program is to make everyone, and especially the rich, dependent on the government. The poor are by definition dependent on someone willing to help them anyway, whether it be the government, a private organisation or a neighbour.
Assistance programs making people dependent on the government is a right-wing talking point and there is no scientific proof of this being generally true. Successful assistance programs are actually designed to give people chances to actually become less dependent on anything, e.g. by educating them on key topics for which there is an economic need. I don't know whether the programs in the US are successful or not and interpretation may even depend on which metric is used to evaluate them but it's certainly not communist.
The rich Democrats don't want to pay taxes, so they tax the middle class to death (28% of middle class income should not be going to taxes).
Not linked to communism, see above. Communism taxes the rich.
Also note, in Belgium (not communist), middle class pays nearly 50% taxes. We're among the top of the world there.
