Easter and COVID19

My in-laws are ridiculous. They still want to have Easter dinner because it will only be 10 of us... that's not how this works! 🤦‍♀️ My sister-in-law, brother-in-law, and their kids have already agreed to go and my husband wants to go... I think it's a horribly irresponsible idea. So now I'm the bad guy if I say no we aren't going and if we do go well you know...let's expose 6 adults and 4 kids to God knows what. My husband and his brother work together so they don't understand boundaries at all. Our state went into a stay at home order last week and my mother in law still wants to do this. What should I do? How do I not end up the bad guy here?

Update #1: I put my foot down with my husband even though he is treating me like utter shit over it. Also text my MIL how we should postpone an Easter family dinner for after the stay home order is lifted because we want to keep them and the kids and honestly all of us safe... She's currently ignoring me but sent a message to the group text one of my 4 SILs sent this morning asking if they were doing Easter dinners...maybe just maybe she got the hint when they said "No!" 🤦‍♀️

Update #2: She finally called me and said she is postponing our Easter dinner until it is safe. Thank you guys for helping remind me I do have a backbone...just have to use it. It's hard when you feel completely gained up on.
