If I am making a reasoned presentation of facts, and all I get is one clap, from anyone I move to block. I take one clasp as equivalent to a slap.. the person is saying , I am here just to let you know I disapprove.
As for those who leave mindless kinds of insults - I block without even bothering to read to the end of their gobshite. I report and block them, so hopefully Medium acts on such hate speech.
Honestly we must be very vigilant, to protect our time and energy and inner peace.
Please take care and make sure you don't take their nonsense on board for even a single instant.
