Actually, yes, yes, yes, and yes, depending on your point of view.
Widespread antisemitism predated the Nazis. Socialism is just another anarchist/labor movement, which were criminalized and demonized by the powerful long before Spartacus. Homosexuality has been brutally suppressed by Abrahamic societies, and wealthy landowners and businessmen have always been criminals to the lower class. These hatreds were not created by decree. They stem from the instinctive fears and resentments we harbor for those who are different, isolated, secretive, or threatening.
So feel free to cloister yourself, hide your differences, and pretend to be a pure, perfect and homogenous member of society. Only don't complain when a dictator comes along, for he will co-opt that false notion of homogeneity to rally the conservative masses, call your concealment proof of your guilt, and use your isolation like a predator who has isolated an animal from the herd.
If you're lucky enough to escape his first culls, you will have the honor of becoming his minion; you will do his terrible bidding, always keeping your head down, always afraid of drawing attention, because of the secrets you harbor, because of the sword of Damocles ever suspended above you.
So consider instead being friendly, open, harmless, and different. The things we accept and embrace in society today, after all, came not from isolation but from ubiquity, and what we call "normal" consists of all the things that showed up and refused to go away. Stand up and politely refuse to sit down. Connect with those who are as unlike you as possible. Not everyone will accept you, but many will, and you'll temper more attitudes than you realize. And in time, when a prospective dictator comes and preaches fear, hatred, and xenophobia, his words will gain little purchase.
