The 'whataboutery' is out of control in your post. Can you hear yourself? Trump does literally demonise other groups - particularly immigrants and transgender people. He refers to migrants as 'lunatics' 'rapists' and 'criminals'.
In fact he only ever refers to undocumented people in this way, despite the fact that the vast majority of undocumented people who are in the US are just trying to work and make enough money to get by and are not involved in violent crimes.
People criticise Trump for doing this. That's not 'demonising' him is it?
"If people can't see that biden has dementia then fine, we'll have to agree to disagree."
The only people who are going to argue that Biden has 'dementia' are people who've never had to care for someone with dementia and don't know what it is or how it manifests itself. Like many older people Biden is forgetful. Sometimes he meanders or mumbles. He gets names wrong. Sometimes he gets a bit confused. Trump has done all of these things himself repeatedly over the past year. But it's only when Biden does this that you insist it's evidence of dementia. When Trump does it you say he's a bit tired. Whatever.
"Trump was president before and i thought it was fine"
The first 2 years of Trump's economy involved the continuation of the economic trajectory started under Obama. And then we had the pandemic - the result of which was that Trump's handling resulted in vast numbers of avoidable deaths. I appreciate that as a Republican you don't care about the deaths of other people, as long as you and your family are ok, but that doesn't make them irrelevant when it comes to assessing the success of Trump's presidency.
And since the pandemic there's been a huge cost of living crisis across the developed world. Inflation in the US only marginally exceeded the inflation rate in the Eurozone, but largely tracked it until Biden intervened to reduce it - since then headline inflation in the US has fallen faster and further than in the Eurozone. I know it's hard for Trump supporters to accept that inflation wasn't caused by Biden - the fact that most of you have no interest in or awareness of world news and international affairs probably helps with this obliviousness.
