How respectable was Darwin?

I am sure it is not just me but many times during my research I am confronted with the Victorians and their views on the world which appear to still influence how we think about many subjects today, notably race, culture, classification, history... I am sure I could go on. Which is why I saw with interest some research done by Dr Gowan Dawson which looks at Darwin from the perspective of was he respectable. Apparently he was accused (through his theories) of encouraging sexual impropriety. Not that I am in any way seeking to discredit our illustrous 19th century forebears...
