I never wear any apparel with ensigns, highly visible trademarks, slogans or messaging. I do not (and have never) used placards, bumper-stickers, yard signs or anything else to advertise my thoughts or sentiments.
I practice avoidance (in combination with awareness) and see it as the most efficient method of personal safety.
Yes, one does possess personal liberty including the right of free expression, but TANSTAAFL. In our current depraved and intentionally, continually sabotaged culture, it will not get better. Entropy demands that it will become worse.
We now live in a culture whereby the mechanism (government) that has general order and safety as its raison d'être is advocating and endorsing (by legalizing) the drugging of citizens with hallucinogens that are causally linked to mental illness.
We now live in a culture where multiple "eradicated" diseases are in the process of resurgence. We now live in a culture where you have to have signage to instruct people in basic hygiene after elimination. We now live in a culture where crazed hostility is overtly encouraged and embraced against those who "fly the wrong flag".
No hats of any kind for me.
