I've not really run into too many people who are jerks about my crossover MLPs, Pokemon, Digimon or otherwise. Actually I run into it more in person at conventions than online, which is surprising! But they usually are okay, people will say stuff like "eww it's terrible" and I'll be like "Nah it's fun! I like them both and I had a good time" and usually then they shrug and let it go. No biggy
