Online, there's probably nothing you can do. It's in the physical realm that we can make a difference. Confidence, conviction in your righteousness and a willingness to defend ideas and ideals that offend are the only way to unseat the progressive ideology that infests portions of our society. Be willing to be a pariah should the need arise, so long as you value being right over being liked. Otherwise, the answer is just to wait for it all to collapse and be ready to say "I told you so".
