Using social and cultural issues as political rallying points is doing the opposite of solving these issues, it's entrenching them as tools to forever rile part of the population against the other.
Many fall into the trap of becoming partisan political activists to "help" with an issue. They are hooked via their good will, and then trapped into perpetual anger and hate that make things worse. That's evil. Evil done to them, that they become, and propagate. Evil viral meme.
