Is it okay not to fight back because you're scared that it might get the situation worst?

It's understandable to not fight back and in some cases yes. One should choose their battles. But if you feel like you're fighting the same thing everyday even when you don't fight back then the situation won't be solved unless you speak up. That might mean it will get worse before it gets better but sometimes that's better than losing the same battle everyday.

Yes. it is. You are thinking of the betterment of your situation and that's good. Also, fighting back is not always the answer. The answer is usually, doing the right thing.

Always defend yourself in any situation, you are a precious human being and being scared is a normal emotion.

Yes. You do whatever you need to do to be as safe as possible. There is no one right thing to do that always works, and you just have to figure out what's the best thing to do based on your own instincts and knowledge. If you didn't fight back and it gets worse anyway, that is the attacker's fault for attacking you. In some situations you may not have the choice to fight back, either, because your unconscious brain may have made a quick executive decision that freezing is the best option. I forget the scientific name for this but it's a thing that happens to both humans and animals sometimes in times of extreme danger or perceived danger--they freeze and can't move even if they want to.

It's perfectly okay not to fight back. The best revenge is no revenge. Some people bother you, just because they want a reaction.

It's absolutely okay. Fighting isn't the answer. If you're fearful of the consequences, it's best to stay away from any physical or verbal altercations that may make the situation worse.

Fighting back isn't your only option. There is always another way if you open your mind up to it.

It is okay, but its not good to let a bad situation continue on for a long time, id let someone know what is going on and have someone that will stand up for you, but violence is never the answer, but stranding up for yourself is always important

It is okay and it is understandable, but it's best to fight back if the situation can surely be helped by it. Otherwise, immediate fighting back my not lead to the best, most well anticipated results.

I believe it is all up to one's personal judgement and set of core values. It is important to fight back, but it is even more important to first weigh the various factors and potential consequences, and then make a more informed personal decision.
