Nobody gets in trouble for searching for and reading about anthrax and chemical delivery systems. But if your ex-wife dies of anthrax poisoning six months later, you will certainly need to have a pretty air-tight alibi to escape suspicion.

The FUD here around "omg if you search for something weird because you're smarter than average the jack-booted Gestapo will arrest you forever!!" is ridiculous.

Strawman argument aside, the intelligentsia has always been feared by the state.

No. If you don't have an average IQ, adhere strictly to what the government considers "normal"; you should be put under surveillance immediately and maybe "locked out of society" for being potentially dangerous.

It's hard to find dangerous people, but it's easy to show huge lists of abnormal people you found...
