I think WPT still does pledge drives - not sure if they did this year as I didn't have cable again until a few months ago.
I'm not going to get in on the gay marriage/marriage equality debate on here, but I do fail in seeing how CLIFFORD promotes the gay crowd, much less any agenda at all. Regardless of anyone's views, their case against Clifford sounds more like desperation to me. Ditto with Sesame Street and most of the others.
I do agree Barney promotes an agenda - the stupid agenda.
Our PBS station seems to have dropped it, thankfully.
