Injections of disinfectants and UV light

I despair.  Why do so many people support Trump.  

It is bad enough that due to Christian values, people have elected an adulterer who is on his third wife over a woman who stayed married to her adulterous husband.  (People have still to explain that to me).

As noted before, Trump has been wrongly blamed for everything in the USA when it comes to COVID-19, but as noted, I do consider his inaction and mixed messages to be responsible for the of spread in many areas of the USA overwhelming services as well as the lack of PPE for healthcare workers there.  (An issue that sadly is present in the UK.)  

I have some idea of why they support him.  His stance on immigration being one.  As noted before, even though his ban will have little effect on immigration, he has been seen to be doing something, just like when he imposed travel restrictions (though not the ban he said it was) on non-US residents entering the USA.  

But his latest 'wisdom' on COVID-19 is just insane.  Injecting disinfectants, or exposing the human body to UVC to treat COVID?  At least his statements on hydroxychloroquine and remdesivir have been about drugs that may be effective in the fight against this horrible disease.  Even if he does not like honest debate on the matter or the fact that other nations need hydroxychloroquine to treat other malaria.  But his latest rant needs someone to explain it to me, assuming that they think that he is talking sense.
