My husband's parents & family on the other hand are similar to the OPs. In order to keep the peace we've taken the approach to limit what they know about our activities. The do know we buy and owns guns (and motorcycles!). (They might know we carry). But we don't ever talk guns or skirt topics where it would invite questions and discussion. If they bring it up out of the blue, we'll talk about it but end it quickly. But we don't bring it up unless there's is absolutely no choice (due to legality issues). Like when my FIL wanted to ship/mail some luggage from AZ to TX which contained a M&P9c
For the most part we keep the things they don't like out of their face. Most of that is out of selfish motivations as we don't want to hear it. We're adults, responsible and take the things we do very serious. We know the risks and for us we find them acceptable. We have made that clear and feel its not something that we have to constantly defend. They like it or they don't, but we have our decisions and we'll continue to make them.
Obviously I can't tell you what you should do. You know your family and what is acceptable and what is possible. Best of luck
