How do you respond to these reactionary questions?

When reactionaries say: "Why do we always have to put ourselves and our cultures last by not serving pork in school canteens because of muslims or allowing underage girls to wear a hijab in school, to let their families oppress them? Why do we let people immigrants live off our government benefits when they haven't paid a single euro in taxes before they came here?"

How do you respond to it? I honestly don't know because these thoughts are so stupid they never even cross my mind so I never thought about it much.
