Is it normal that my dad is becoming less liberal and more ignorant?

Let the old fucker die in his own painful misery.

Make a plan to distance yourself from this destructive behaviour pattern, should he not decide to make a concerted effort to conform with a new reality.

Make your intentions known to him, discreetly.

Less liberal does not equate to more ignorant. There are good ideas on both sides, but the extremist on both sides try to prevent any common ground between the two sides. Because of the extremist in this country, the country is headed for a HUGE civil war (bloodbath). I hope you and your family find a way to live with each others likes and dislikes, peaceably

Maybe he's had a stressful event in his life, such as trouble at work or an emerging mental condition, that caused a drastic change in his personality. Alternately, maybe he realizes that he's losing control over you as you approach adulthood, and he wants to regain some of that control by criticizing your choices.

Next time he makes disparaging remarks about a new activity you like, tell him how you feel. Say something like, "When you make flippant comments about something I'm intersted in, I feel hurt and disappointed that you aren't interested in learning about what's going on in my life." You could also explain why these activities are important to you, i.e. "Kickboxing is my way of taking care of my body and staying in shape." What parent could fault their child for wanting to exercise more?

Since he was understanding in the past, it's possible that if you talk to him, he may wake up and realize that he's driving you away. If the negativity and name-calling persist after you talk to him, then it may be prudent to go no contact for a while once you get out on your own. Your parent is the last person who should be putting you down.

Wall-O-Text. Does not compute.

I don't understand where politics come in here. Just because someone lets say, doesn't accept homosexual marriage, doesn't make that person a conservative. And being a conservative doesn't necessarily make you an asshole. If the conservative party actually believed in its own ideas they wouldn't make a half bad party, but they spend just as much money. At least, the canadian government has been an example of this.

Maybe it's as easy as, Dad, I feel like you've changed, you never used to do this, that or the other thing. Be careful though, he seems like he's sensitive, but the last thing you should do is cut contact with him.

You got it wrong.
Per Michael Savage... Liberalism is a mental disorder.
Sooner or later you run out of everyone else's money

Well, shaving your daughter's head in any form is assault unless she wanted it done...

This isn't about liberal vs conservative. There are plenty of conservative people who don't talk like that to people even if they don't agree with them also there are also plenty of liberals who talk like your dad to people they disagree with and vice versa. Perhaps your dad is getting resentful that you are growing up and making your own decisions independently of his ideas and opinions. Are you parents having any marital problems? So far to me he just sounds grumpy. Maybe your folks are having money problems.

Code is broken.

Need better deciphering skills.

Good
