european ancestors did. we must expell the muslims and the talmudic-kabalistic jews from our countries we must ban freemasons.
Should look into your ancestors a bit more. Europe has never decided on anything as a whole, let alone banning/expelling a partiuclar organisation.
You will find individual countries have tried to controll the masses and suffogate groups not in accordance with govermental, dictator, or overlord controlled countries. (which adjective you use will depend on which country and how far back you go)
And not everything that goes wrong or you disagree with is down to one group, trying looking past your scape goat.
