Yes. It just takes time and effort.
I changed my position from Christian to Atheist.
I changed my position from anti-gay to pro-gay.
I changed my position from eating meat to not eating meat.
I changed my position from being strongly anti-American, to realising that position was stupid.
I was anti alcohol and drugs, and now I am pro.
It just takes effort and a willingness to address where you may be incorrect. And it's hard. A lot of these positions are deeply cherished, and we're not good at rationally weighing two sides when we already ascribe to one side. It's not easy, because confirmation bias makes it easier to dismiss counter arguments than to weigh them fairly. And most of us are aware enough of this to suffer from cognitive dissonance, and it takes a lot of effort to get around that.
