Dal Khalsa is a group of Sikh people who believe in fighting for their rights and the rights of other Sikhs.
Imagine you and your friends all like playing with toys, but sometimes other kids take your toys away or don't let you play with them. You would feel sad and maybe even angry, right? Well, that's how Dal Khalsa feels when they see other people treating Sikhs unfairly. They want to make sure that Sikhs have the same rights as everyone else and are not discriminated against.
But Dal Khalsa doesn't just talk about these things, they take action. They form a sort of "army" to fight for Sikh rights, but not with guns and bombs like some armies do. Instead, they use peaceful protests and demonstrations to make their voices heard. They wear special clothes and symbols to show that they belong to the Dal Khalsa, like how you might wear a superhero cape to show that you are a superhero.
However, just like with superheroes, some people don't always agree with what the Dal Khalsa is doing. They think that they are causing trouble or being too aggressive. But Dal Khalsa believes that they are doing the right thing by fighting for what they believe in.
So, in conclusion, Dal Khalsa is a group of Sikh people who use peaceful protests and demonstrations to fight for Sikh rights and make sure that Sikhs are treated equally.
