On the topic of circumcision, that's still recommended by the CDC. While I'm not anti-covid-vaccine, it does make me question whatever recommendations they have. That's something specific to the US but most countries have something fucked up if you search for it.
Human population planning, forced (not mandated) vaccinations, circumcision (recommended, not mandated/forced), etc... are all in the same of governments/govt. org's forcing, mandating, or recommending something concerning and individual's body. With how most laws are passed/worded, I'm sure there's some crossover in extending powers when it comes to things like this.
With the vaccine rolling out, I think the question for governments should be how to get the skeptical people to trust them in that taking it is safe, not "how are we going to force this on them". If they did a good job handling the situation, I'd imagine they have less people skeptical of their advice.
At the end of the day, however things play out, you're either a victim of - or thankful for - whatever country you're living in. Everyone's privy to their opinions, however. So if you can vote on said issues, vote, and keep yourself informed via trustworthy resources. The shit people repost on Instagram, FB groups, etc... it's insane how so many people are quick to take that stuff as truth.
