Can you defend who you are as a person and what you believe in from jerks on the internet?

No. What would the point be?
Most people tend to get obtuse if they have a bad opinion of you anyway. Best to leave them with their opinion.

I'm able, I just don't care too much. It's a waste of energy and life. Most humans are fixated on their own perceptions and beliefs. So why would I bother with it much...

I guess it could depend on the person and situation.

I'm done defending, because more and more I realize that their words are irrelevant. So it's no point wasting my energy on convincing or proving something to anyone.

I have encountered rudeness and don't think I need to defend myself towards individuals like that. My time is too valuable to waste it on them. 😌

You can,but often relevant points made are ignored or scoffed at.When this is the case,its a waste of time bothering,in my opinion.

yeah because im a decent human.

Easily. If you cannot express why you choose to take an action or commit to an ideal, you should think more about why that's who you are. That's just as true online as it is in-person.

I don't even try to.

Always, a political left wing socialist.
I also live as a girl.

Yeah, Zionists, queerhaters, Fascist, tranny beaters, Nazi's, narcasists and tory gender bashers.

I can fight my corner, I have long nails!

I can do it but 'jerks' are wums or so sure of their own opinion that it won't be changed so it would be a pointless exercise. (I respect people who can admit when they are wrong).

Some are intentionally difficult to debate to on the internet. Some are even phonies.
My concern is when they groom others into their lifestyle while they are weak and hurting.

Not too hard, you just ignore the ignorant and stupid aka Liberals

I can defend my beliefs but who I am matters not

That’s a waste of time

If I had to.
