Every time I look at that I read that the extreme tactics were controversial at the time and still are.

I’m sure you can find the wikipedia article, but here’s a relevant quote.

“Searle says the methods of the suffragettes harmed the Liberal Party but failed to advance women's suffrage. When the Pankhursts decided to stop their militancy at the start of the war and enthusiastically support the war effort, the movement split and their leadership role ended. Suffrage came four years later, but the feminist movement in Britain permanently abandoned the militant tactics that had made the suffragettes famous.”

And if you think about it, there is obviously some limit where extreme tactics will hurt more than help. Would you advocate bombings because some suffragettes used that tactic? Burning cars?

Civil disobedience is a critically important tactic to get attention and drive change, but we should be able to discuss particular tactics and not just say “but the suffragettes”.
