I collect many different things...niche RPGs collector's editions, board games, lots of different books, and of course figures. I don't get many inquiries into my collection and when they do I just say oh it's all good. I don't argue or anything. Most people wont understand what you're into and if they're generally interested into getting into it....well tell them of course! All I know is if people don't understand or put it down or such, if they're just some "friend" I will likely blow it off and if the person is being mean just ignore them and not be so inviting...but other inquisitive souls...I just say I like it and leave it at that. No need for discussions really unless they really want to know more to get into my hobbies as well.
