Assuming you've been paying exactly zero attention to anything going on, here's a few major things that he is responsible for:

Travel ban targeting Islamic countries

Withdrawal of Paris Agreement

Fired head of FBI when Comey wouldn't declare personal loyalty

Issued a directive to the department of health agencies "waive, defer, grant exemptions from, or delay" portions of the ACA

Soon to be pretty closely tied to:

Tax bill making graduate school significantly more expensive

FCC votes to kill net neutrality next month

These are, in my opinion, the worst offenses. There are many other things that he is either responsible for or closely related to. A simple google search yields list after list of things he's done both large and small.

I think the major fear is the precedent he sets for divisive politics in the future. He also may cause the US to loose ground to China as far as foreign influence goes, but the first point is what worries me.

I think the politics were divisive before. In fact, I'd claim that Trump's election is the result of divisive politics.

The purposeful gutting/disorganization of major federal agencies and operations, the discrediting of the white house's statements, the undermining of existing federal law (see: explicitly sabotaging the ACA), then there's, of course, aiding and abetting enemies in order to win an election.

What exactly is it you mean these things show? Sounds mostly like you are complaining about his form than anything he has actually done.

Is it worse than Bush administration who started a war?

I just don't know how else to tell you that these things are all very bad. They, to me, should appear bad at face value. We clearly differ in the perception of the world at a fundamental level.

Even if they are bad are they as bad as Bush starting a war?

It's claimed that somehow Trump is the worst of them all. From what you have stated here do you personally think they are worse things than Bush starting a war?

I find it really hard to believe you're arguing in good faith. What is the purpose of a comparison to Bush..? Even if the answer is that Bush was worse, it does not take away at all from how terrible Trump has been. And we're comparing 8 yrs of Bush to not even 1 from Trump, here.

Anyway - yes, I do think that conspiring with hostile foreign entities to manipulate voters and undermine American democracy is worse.

Well believe it.

The purpose is to test whether the claim that Trump is somehow worse than everyone else based on the mentioned examples of his bad deeds really holds up to a sanity check.

I think your last sentence much better illustrates who of us are in good faith here though.

While I have an opinion for your question, you seem oddly driven to change topics. So I'll kindly decline to answer.

I am not changing topics at all. When someone claims that Trump is the worst we have ever had then that of course means we have to compare to what other presidents have done to determine whether this is mostly a disagreement over style or over actual politics.

The later is interesting the former is boring.

So... typical politics or unproven allegations. Got it. Not like... starting wars (like 4 previous presidents have done) (although he's still got time, I'll give you that).

I know 2 data points do not make a pattern, but it's really weird that both replies to my comment are in a similar vein from usernames that appear to be variants of "Tom P"
