I don't like Winston Churchill.
Granted he was a very complex man, much given to uttering extreme verbal outbursts on whatever position he held that moment, replaces a few hours or weeks later by an equally exaggerated outburst on the opposite view on that same issue.
So it is easy to find vivid quotes from him displaying both humanity and brutality towards the German Jews and Leftists who fled Hitler for Britain before 1939.
For brutal , see his comment 'collar the lot' as soon as he became PM in May 1940.
