Ask HN: Is it unwise to post conservative opinions as a tech worker?

I've been in tech for over 15 years and have never posted publicly under my own name any political opinion. I'm not sure if I'm being a coward or prudent. I used to identify with the left but now I lean conservative, and I feel like there is a huge bias towards that in tech. And any opinion can only hurt me if they look me up. Please let me know what you think on this matter.
