If the Left thinks Nazis are bad then why does it adopt Nazi behaviors?

Ok the Alt-Right is getting plastered with Nazi rhetoric lately. We all know the Nazi behaviors the Left is focusing on there and saying why the Right is so bad: Racism, racial purges, ethnic purity, all that line. They've even pointed at how Trump doesn't allow the left media to cover him. BUT if the left believe Nazis are bad I have a question: Why does the left adopt Nazi behaviors?

1. Mandated Health Procedures: Namely Mandated vaccines but this could be any mandated health protocol that is required by the state. Look I'm not going to debate the validity or the merit of any given protocol here. You could be injecting saline solution or giving patients an elixer of life to make them immortal. It doesn't matter. The point is the state doesn't own one's body and one should be able to refuse any medical procedure. The Nazis did medical experimentation on the Jews. That's WHY the Nuremburg Code was implimented and WHY we have this set of ethics. So if the Left hates Nazis so much WHY on earth do they push for ANY mandated medical procedure. If the Left hates Nazis then shouldn't the Left be championing medical freedom not pushing for mandated vaccination?

2. Censorship: Both the Left and Right use censorship. One of the biggest tools of the Nazis was propaganda and censorship. Yet censorship is becoming rampant on the left, within mass media and internet tech companies.

3. Eugenics: The Left champions euthanasia, abortion and even identifying if one's child is going to have a disability and then offering the choice to abort or not. This is eugenics! The Left also champions genetic engineering which leads to human genetic manipulation and designer babies. The Nazis would have killed off everyone with a disability or who wasn't pure. So much emphasis is given to the death camps and holocaust that people often forget about the breeding programs and the fact they were in fact practicing eugenics.

4. Revisionist History: I've been seeing A LOT of this lately. Tearing down of monuments. Censoring of films. Rewriting of textbooks. Editing of history to try to edit out the "uncomfortable" parts. Yet another form of propaganda. Not saying the Right isn't guilty of this as well.

5. Political Violence: One of the big things neo-nazis and white supremicists are accused of is attacking people for believing or being different than them. But more often than not I see those on the Left initiating violence. Big question tho is why? If political violence is wrong why do it? If it's okay for YOU to do it then why is it not okay for THEM to do it? And wasn't WWII one big spat of political violence? So if you don't like Nazis and don't believe in political violence then WHY DO IT?

6. Mass Medication: Putting ANYTHING in the air, water, or food supply and medicating people en mass against their will is not only a violation of the Nuremberg code but it's straight out of the Nazi handbook. In point of fact the Nazis used Fluoride to keep the Jews docile. It is a neurotoxin. But the larger issue is: Mass medication is something the Nazis practiced and believed in. So why is it something a lot of Left Wing states and countries are doing and/or pushing for?

I'm not trying to say the Right hasn't adopted some bad behaviors too. The border checkpoints and random searches, or warrentlless searches come to mind. Or various incidents of police violence and police state mentality, not to menton general authoritarianism. But what I am saying is the Left doesn't have rainbows shining out it's ass either. If the Left is going to define itself as anti nazi or anti fascist it needs to clean up its own act first. You can't be anti fascist or anti nazi when you are adopting their behaviors.
