The only people who have a problem with others blocking them are those who get upset because nobody wants to discuss their ideas with them. I block all the time. I don't have time to discuss everybody's ideas with them. i don't write to change the world. I write my own opinions, accept that they are only opinions, and I have no desire to waste m time thinking that they are going to change the world. I am not so stupid as to think that anything I write can change the world.
