If whites acted as a community as blacks or Jews did, we would be increasing our population numbers, earning even more money in our jobs than we currently do, etc.
Not a single white writer will NEVER speak ill of other whites for something "related to racism" until every black, Hispanic and Jewish writer speaks ill of racism for his own people. Otherwise, we are contributing to our own decline.
You can no longer blame others for your problems … I say this as a white man. First, take responsibility for your own life: be proud, trust, go to the gym and be muscular, take care of yourself and take care of your appearance. Shave and look good. Dress well. Smells good. Wear cologne And take your attractive appearance and then convince other white people, in your daily life, to feel confident and proud of themselves. Do you see a white couple with a new white baby? And are you a friend or do you know that person? Congratulate them on their new baby, say how beautiful it is and, in jest, ask when it will be next! Tell them you are very proud of them. Make them feel good by repopulating and having a baby. Make them feel proud of themselves.
Similarly, if a white person speaks ill of other whites or denounces whites for racism, simply look at them as "…. wtf dude?" and show them negative emotions, make them feel stupid and embarrassed by talking publicly about their own people. Even if you do not say it directly, make them FEEL from their facial expressions. Then you can say something like: "Does it bother you when there are many examples in the registry of blacks, Hispanics, etc. that are racist for you and your own people? Or do you only care when the whites are racist?" If they do not have a good answer for that, just look them in the eyes in disbelief until they feel uncomfortable.
When the whites, as a people, regain that confidence, that self-confidence, then their actions will naturally follow, and they will stop acting with such fear and self-esteem and self-denigration.
