Generalization is not 100% but it is a majority. Based on your posting you think that generalization encompasses a 100% of a certain population but it does not. You are giving an example of two black doctors in your neighborhood and telling us that they do not just vote democrat because of welfare. Of course they will not just vote democrat because of welfare since they are making money and a lot of it. However these two are a minority among blacks and in your case you took the minority case and you want to make it a general case to build your argument.
A majority of blacks vote democrat because they want more governments handouts, entitlements and affirmative actions. That is the fact.
