Toxic people will always be snarky and sarcastic when you're winning at life. That's how you know that they're toxic.
The envy that they feel is channelled into cutting you down. This is particularly vicious with people with an entitlement mindset. They hate feeling inferior and they feel a deep need to cut you down to size when they perceive you're getting "too big for your britches."
Honestly, this is loser behavior and should be recognized as such. Engaging in debate and going back and forth on a real substantive argument is one thing. Snark and sarcasm is almost always toxic envy. Sarcasm is not argument. Snark is not reason. Sarcasm and snark are emotional weapons to sideswipe logic and reason. Toxic people do this to make you submit to their frame, to get you to emotionally abandon your position rather than rationally be argued out of it.
Sadly, this is how most of the world works. They are not convinced by argument, but by tribalism and emotion. In a fiat world, such tactics are extremely effective. It's called peer pressure and it robs us of our individuality. Becoming immune to such peer pressure is exactly what thinking for yourself means. Hence, cutting toxic people out of your life is not just healthy, but necessary if you want to grow.
What's nice about the Bitcoin community is that there is a deep respect for real argument, particularly from first principles. That's good because the fiat system lends itself to centralized groupthink. And centralized groupthink will have its share of bullying, toxic Karens.
Thankfully, we can cut the toxic people out of our lives under a Bitcoin standard and leave them powerless to influence us, but to do that we need to not just get on a Bitcoin standard, but also change our mentality to be self sovereign.
