That seems like overinterpretation to me, based on the ideological battle lines of the moment. Even if you're right, though, I think people mostly do that because they want to stand up for someone.

Edit: maybe it would be of interest to add that, from the therapeutic work I've been involved in, it is clear that people's motivations in these areas can often be traced to family dynamics—which is to say, to love. Even when it doesn't look or sound like love, love is usually the driving force. I often think of Chesterton's line, "The soldier fights not because he hates what is in front of him, but because he loves what is behind him". You can say the same thing about political and ideological battles, which after all are (quoting a different celebrity) war by other means.

This is an optimistic view, because the more we can see and acknowledge that love in each other, the less we need to be in conflict. The challenge is that such love often goes through complex transformations and distortions which can be hard to disentangle.
