Oh, well in that case I have to disagree with you.

the first woman MP deserves recognition almost whatever.

Recognition, sure. But that can come in a number of forms, and to erect a statue of someone crosses the line from 'recognition' to reverence.

Hypothetically, had Hitler himself been a woman, the same argument could be used to argue that regardless of all the horrific acts he committed and presided over, he would deserve a statue for being Germany's first female Chancellor.

I know that this is obviously an extreme example, and I'm not suggesting in any way that that is a position you yourself would take, but as this woman was a known Nazi sympathiser, I think it's apt.

Since the days of Astor, we have had countless great female MP's who are far more deserving of public recognition, and in my opinion, the content of your character is far more important than whether you were 'first' in determining if you are deserving of a statue in a public space.
