It seems obvious to me that painting yourself a few times a week would repel biting insects by masking your body's natural aroma with the smell and physical barrier from whatever chemicals are used in the paint. I mean if you are going to do this, you may as well throw some citronella right? While it may be interesting that black and white stripes also have an affect any practical application of this is bad news for meat eaters and our environment as these paints as used by your local rancher will not be made out of stuff that is okay to soak your food in before eating.

This is the same as a landlord advertising in GQ or Penthouse, just because facebook is able to offer more accurate reporting does not criminalize an effort to appeal to the people you want to attract. Personally I think facebook is crap and cancelled my account the day trump got elected but if advertisers want their ads to go to only men that is the advertisers goal and should not be a crime in general.
