How to stay sane? It may feel irresponsible with the world falling apart around us, but focus on other things, especially things that are constructive (whether that means creating something that you think will be helpful to others, taking pride in doing your job or finally giving your house a good cleanup). It's hard to stay grounded if you spend all your free time reading about this shit, watching videos or trying to win discussions about it.

If for whatever reason you can't get away from dealing with this (or if you can handle it), then try to organize locally. Most people IRL are normie moderates who believe whatever news sources they follow - they might not agree with you but they're probably just well-intentioned but ignorant. You can help them build up mental defenses against the far left's emotional arguments and constant gaslighting, either directly or simply by helping to bring out whatever latent appreciation of property rights, the family unit etc. they already have (but have never really had to think about).
