It seems odd. I hardly ever have any problems on Deity with Ideological Pressure. Usually you get to Ideology first and that basically means you can build the Eiffel Tower which will give you plenty of time without pressure. I also usually make my Ideology World Ideology helping very much as well. The one recent game I went Freedom when the rest of the world went Order I had -32 Revolutionary Wave and only -10 happy which I could of easily got out of the unhappy but I decided to switch to order bringing me to +25 happy. I did lose that game by one turn but it was because I was experimenting with Freedom and I decided not to war with my very large Army and all the Military CS's next to me that had huge Armies that I had control of (Monty was Afraid begging me not to attack and I did not even have Nukes up yet!). I really played dumb where I went warmonger right from the start and I figured I could just turtle and win and I never got the war going but I should of cause I would of taken over my Cont very fast. Lesson learned but like I said before I hardly have any problem with Ideological Pressure. A couple of games ago I played with -32 Revolutionary Wave but my happy was something like +20 the whole game and I never had a problem and finished that game with a win on Deity as well. I am not sure what you are doing to get this problem but for my games Ideology is not Broken and seems to be working the way it is supposed to. All of my games are on stand/stand settings. When I am warmongering and get into this happy problem I either Raze or Sell the cities that do not matter and that seems to fix any happy problem.
