If anyone is basing their morals specifically just to go against their "rivals", I would seriously question that person's ethics, empathy, and reasoning skills. I'm absolutely serious about that. I would not trust that person in real life.
I would also have little sympathy for anyone who makes their own life worse just to get one in on their "rivals". You should always think how a new law might expand in 5-10 years, and not just focus on the current emotions.
If someone who you considered to be a truly terrible person got into power next, would you feel comfortable with those groundwork protections being seen as changeable? Would you be ok with that terrible person having that level of say over your life, knowing that they would get away with it?
If you hypothetically start messing with things like your country's ground-level human rights, it's likely to only be a matter of time until everyone is effected by it in unpleasant ways. Everyone thinks these changes will magically stop before it hits them, but I would strongly recommend for these people to brush up on history again. How has that gone in the past?
Politics shouldn't be some lame "gotcha" game because politics effect the real lives of many people. If anyone wants to do "gotcha" games, there are many places for those that won't possibly end with someone dead. That "someone" may be a stranger today, but it could be your child, spouse, or best friend next time.
