People who only respect people who have the same opinion as them.
They find everyone who has different opinion than them very rude.
They don't believe in freedom of word.
If you say or write something they disagree with, they are most likely to fight you.
They really dislike hearing things they disagree with.
These people are often American teenagers (mostly female) who didn't experience communism in their country.
Modern communists are called like that because when there was communism in Slavic countries, people weren't able to express their opinions and when they said something communists didn't like, they made sure that they badly regretted it.
Example of conversation:
Person: *uses constructive critism or says/writes any unpopular opinion or something that modern communist disagrees with*
Modern communist : DIDN'T YOUR MOM TEACH YOU THAT IF YOU HAVE NOTHING NICE TO SAY THEN YOU SHOULDN'T SAY ANYTHING AT ALL!?
Or:
Modern communist: OMG, SHUT UP, IT'S 2020!
Or:
Modern communist: OMG WHO ASKED?
If any person tells you to be quiet because of your opinions, then they are a modern communists.
Example:
Did Charles just tell you that you should shut up because it's 2020 and your opinions aren't cool enough in his opinion?
Then Charlie is a modern communist.
