Okay, a point of clarification...
I am against cynicism - not trusting or respecting the goodness of other people and their actions, but believing that people are interested only in themselves.
I do think we should all try our best to trust and respect the goodness of others, and their good actions... and we shouldn't always attribute the worst motives to others.
And I am for sarcasm - remarks that mean the opposite of what they say, made to criticize someone or something in a way that is amusing to others but annoying to the person criticized.
Think David Letterman, or Larry David, or even Jerry Seinfeld... sarcasm is a useful tool. It's a protective strategy, gives us a little mental space, and it's a great weapon to puncture & deflate those who need puncturing & deflating.
Good for mental health.
Also good to adopt a "healthy skepticism" - nothing should be accepted nor rejected without considerable evidence - seems super-relevant, useful and important in this crazy world of disinformation and propaganda!
Go forth, be fruitful and multiply the good works, thoughts and actions...
