Sales Tax isn't determined by public opinion.
You need to consult with the taxing authority in the specific area in which your business would be located to find out what your obligations towards charging it are. If you are legally responsible to collect sales tax and you do not, the taxing authority will force YOU to pay the taxes along with a whole slew of penalties and interest.
Attempting to dodge the tax authorities isn't a good idea either. In the US they can go back many years and oh do the taxes, penalties and interest add up fast! I've worked in Sales/Use tax and gone through many, many audits and every single audit has ended up somewhat pricey and these are large corporations who were doing their absolute best to collect and remit sales taxes properly.
