Hey man, I think you might need to do some more updating to your site, I saw theres a "this was cancelled" note on one page, but if you enter from any of the supporting pages you are given different and false info. Here are 3 places that still state that you are having the expo this weekend.
I would just also like to note that I never had a chance to visit this event, but it seems like there might of been too much of your own personality and opinions pushed into your business that could of effected it as well as anything else. Upon visiting your social media pages I realized that they are being used to promote your political opinions and it definitely seems like it is getting negative feedback, including the general concensus that this hobby is something we do for enjoyment and to escape the landscape of political propoganda. This expo seemed like an awesome opportunity for the community, but it also seems like you immediately turned to blaming the community when things went wrong, when there is obviously other issues with the format and admin involved.
Im sorry that this had to happen, and hopefully this will be a learning lesson that will sprout the need for something new and exciting for our community. I hope you're able to be a part of it as well Max.
