Covid and seeing people

We are still staying safe and haven't seen our friends or most family since this all started. (I'm from USA so it's not good here)

Our in laws invited us over but they also invited my BIL and his gf who are all over the place (parties, restaurants, basically no restrictions). And I don't feel comfortable because I have a child and the person I take care of as my job is immune compromised. We are taking all precautions but it's starting to cause some issues for us with friends and family who want us to just 'get over it.

Is anyone else having this problem where you are staying safe and doing your part and others are not and they are upset with you?
