The word Hashkafa means looking down (Rashi in B’raisheet), i.e. condescension . Being that a person doesn’t make himself into a rasha, he creates a philosophical construct to justify beliefs and actions. Often that sheds a bad light on others. For example, pro/anti Medina. Each side sees the other as morally off base.
Are there core beliefs and tenants of out faith? Of course, but we should realize where they end and other ideals start. BTW, I’m still working on it.
