The one thing that can be said about Paisley is that he is consistent.

He has consistently blocked any attempts at peacemaking

He has consistently been hypocritical about violence in Northern Ireland

He has consistently refused to make any concessions whatsoever whenever any plan for a settlement in Northern Ireland has been discussed.

He has consistently been a rabble rouser and general trouble maker.

He is possibly the British Isle's most loathsome politician of the the 20th century. (though I can think of at least one other candidate for that title)
