I can absolutely understand the sentiment with regards to certain ads but it's definitely out of the users control here. What ads are run is determined by Tapas' ad provider, which I would assume is Goggle's Ads/Adsense, and we all know good ol google
but being a little less pessimistic I would hope to assume that most folks would be smart enough not to assume that a creator/site's views don't align with the ads run on the page. As for solutions I think all that can be done is attempt to reach out to Tapas or wait till voting season passes.
I've seen my fair share not only on Tapas but YouTube as well and all that can really be done is either scroll past, skip or ignore it. And if you're adamant about making sure people are aware of your stance maybe a small banner or something could work
