In this case, I think saying he liked Hitler is actually weakening your argument, even if it’s completely true, it’s clear from the reading that he wished he could personally kill hitler, but found him charismatic, and is saying that charisma is what his success was found on.

All of what you said there might be true, and all of that makes your case that he was a bad man better, but doesn’t make the case that he liked him better. At the end of the day, you don’t like someone you wish you could have killed. Saying he liked hitler when the reading makes it clear he wished he could kill him makes your other claims more dubious, not stronger, you should probably refrain from that in the future if your goal is to convince people.

All of those things may be true bad things about orwell, but none of them means he was clearly a fan of hitler.

Furthermore, I think antagonizing orwell, even if he was bad is just bad praxis for convincing people to be anti-capitalist.
