Here are a few alternative boards to /pol/:
>>>/n/ : Global news board. They have a 500-character requirement for posting new threads, but it can be a pretty good source of info when /pol/ is shit
>>>/liberty/ : has a large libertarian-leaning userbase, but they have lax rules and allow all political discussion of any type
>>>/new/ : mostly a dead board, but could be worth reviving. They have a rule against spam, but otherwise they have pretty relaxed moderation
>>>/pn/ : The only rule for /pn/ is to follow the global rule, though it's intended to be a politics board primarily
Take your pick, spread the word, and maybe one of these alternatives will eventually reach critical mass.
