How to get my parents to stand up for me against bullies instead of apologizing to avoid any confrontation?

Talk to them. Sit down and have a serious talk with them about how you're feeling and how their simple apologies make you feel. Tell them you want them to stand up for you and have your back. Just tell them what you're feeling.

Well, you should respectfully and calmly tell your parents how you feel. Instead of saying, “You never listen to me!” or “You’re a weakling!” or “You never face problems!” or “You’re not brave enough!” you should try not to focus on saying you so much and saying what they did wrong. Keep saying I and me and tell them what they can do right. For example, say, “My feelings are hurt about the bully, and I think that you should tell the bullies’ parents about this. This is a problem that is bothering me and I think I might need your help. Can you take calm, nonphysical action?” Try to keep it kind and personal.

By being open with them , How this is really effecting u and telling them that no body can help them

Try explaining to your parents that apologizing doesn't do much, and that bullying really affects you and hurts you.

Be honest with your parents about what is going on with your bully and make it clear that you are asking for their help and not just a simple comforting word or gesture. Keep in mind that like you, they're human, and that it may be difficult for them to know exactly what to do in your situation. But if you are there to help each other over come your bully, you're going to be on the right foot!

Explain to your parent the way this makes you feel. Many parents do not understand the emotional and physical impact bullying has on young people today. They may see this bullying as just a small part of your life but struggle to understand the magnitude of the stress this may put you under. Try to explain to them why apologising is not working for you, although this may seem like the easy option, try to make them aware that this does not make life any easier for you. Try to put them in your shoes in a way it makes it easier to empathise with you and fully understand your situation.

So, you're feeling like your parents don't stand up for you instead they avoid confrontation at all costs. Starting a discussion letting them know how you feel may help.

I think you should have a sit down explain how these bullies are making you feel and what you think their confrontation would do to stop them.

If you know the bully's parents name you could tell it to your parents (they can call them, Message them, or simply meet up to discuss whats going on between there children)

Show them you are emotional or set an example, stand up for bullying and show them the way and they shall follow.
