Ignore the negativities. Try to be honest which is itself a challenge here but if you do then others may follow.
Yes, that's basically it.
You function by minimizing your exposure to harmful effects. This is how in psychology you should fight toxic people like narcissists. You don't talk to them, don't engage in any activities with them, basically cut ties. If the society harms you cut yourself from it. Don't use social media, delete toxic contacts, phone numbers, don't believe commercials, don't watch tv. You have to filter information and watch only what you believe is worth watching.
You will do the same if you had the chance.
So it is normal to be part of this system and function into it.
No, I would not.
Don't allow yourself to be manipulated.
