Having a political view and expressing it in a comic book is not going to alienate me, even though I find the subject extremely tiring IRL. Heck, it can actually be really interesting if it's written well. But if a book clearly has no purpose other than to throw out a political view, and does it in an anvilicious way, then I get annoyed.
I'm in a situation pretty similar to yours, but my solution is to not read current comics and just buy old issues through a digital store. Not that I don't own some physical stuff, but I really am saving a lot of cash by going mainly digital.
So, this redesign is supposed to make the site easier to browse on tablets? That's good, I'm getting a Kindle Fire for my b-day to replace my ancient laptop, so the more sites get optimized for tablet use the better it is for me.
