I wanted to give them the benefit of the doubt in that regard, but many of those groups aren't "liberal" so much as they are socially progressive or charitable.

It's especially suspicious in that they have separated "liberal" from "Democratic" and "Republican" party and candidate giving specifically, a detail that you will see with a brief glance through the comments has escaped most of the great minds of Reddit. Especially especially because so many political parties outside the US that broadly share those views simply go by the Liberal Party.

The inescapable conclusion is that OP either has a clear agenda and knowledge and has phrased his post deliberately misleadingly or they simply have an extremely inaccurate definition of liberal... and an agenda.
