1- if you cant even endure an opponent on internet then you cant endure democracy too.
2- if you cant even sustain an opponent on internet then you cant sustain democracy too.
3- if you cant even tolerate an opponent on internet then you cant tolerate democracy too.

if they all are correct then please tell me which one is more common.
thanks

I think I can see what you're trying to say, but you will need to change it more than you have: If you can't even tolerate opposition on the Internet, then you won't be able to tolerate democracy, either.

"Endure" is also possible, but "tolerate" is the meaning you want, I think. "Sustain" is wrong for the first clause.
Hi enoon.
thank you so much for answering me.Emotion: smile

why you changed opponent to opposition?

and :

I think. "Sustain" is wrong for the first clause.
because of its meaning? because it can also express "supporting"?
Students: Are you brave enough to let our tutors analyse your pronunciation?
If you can't even tolerate an opponent on the internet, then you can't tolerate democracy either.

I like enoon's use of "opposition" better.

An opponent seems like more like a single person rather than general opposition.
MIGwhy you changed opponent to opposition?
Because what you're tolerating is the actions of the opponent, opposition, not the opponent himself.
MIGI think. "Sustain" is wrong for the first clause.because of its meaning? because it can also express "supporting"?
For the meaning, and yes, because it is certain to be misunderstood the way you say. Anyway, for "sustain" to mean "withstand", the thing sustained has to be patently injurious, and an opponent is not. Even if it was, you do not mean "withstand", you mean "stand for", a way of saying "tolerate".
Emotion: smile Thank you both. i got it.

sorry i forgot this :
in my language i can use endure before a person name to say i don't like him because he is annoying to me.
like :
i cant endure john.
or i have to say :
i cant endure his existence or i cant endure his behavior.

i think i found the answer.
"i cant stand him/her" is how you say it in English.
Please always capitalize the pronoun "I".

We can say, "I can't endure him", too. That is a little different from "I can't stand him." "Endure" means he is annoying. "Stand" means you despise him.
I really appreciate your help.
Thank you enoon.
