I don't want to find myself in a position of defending Dodgson, because I have no idea what he was like, never having met him.
For all I know he was a child molesting paedophile. The point is I DON'T know - and neither does anyone else. There simply isn't enough evidence. He has had a large number of biographers, some of whom can be seen to have written rather a lot based on very little. Some researchers have based decades of their life on Dodgson and still there is no definitive opinion one way or the other - and I strongly suspect we will never know because we can never know.
Unfortunately - a lot of people are happy to base opinions on speculation.
