What’s so bad about allergens that your body would rather kill you than let them enter?

Question

I know allergies are really common, but I don’t quite understand what’s so bad about pollen, peanuts, etc. that you body would rather shut down your airways entirely than let them enter. What exactly would happen if they did get in?

I think that it is more that your body responds BECAUSE they entered your body than to prevent them from entering your body.
