In my experience, how you say it matters at least as much, perhaps more so, than your actual point.
You should be trying to bring solutions, not complaints. If the entire point of your blog is to kvetch, then don't make it a "political" blog. Make it clear "this is me bitching into the void." It will be less likely to come back to bite you.
When you bring solutions, be incredibly careful to not point fingers.
The English bible says "The meek shall inherit the earth." My understanding is that the French version says "The nonchalant shall inherit the earth."
Try to be nonchalant. Try to be diplomatic. Try to educate people rather than lecturing them.
Many blogs are just noise anyway. Having big feels about something doesn't guarantee you will have anything of real value to contribute. But if you think you can make a difference, then, there are ways to be more Zen about it.
"If a tree falls in a forest and there is no one there to hear it, it makes no sound. Yet, it falls."
Depending on what you write and where you apply for work, it may or may not affect your career. It's ok if your career is more important than what you want to say about political topics...the average political essay is noise.
It's also ok if what you have to say is more important than your career. There's no right answer in the abstract.
Good luck.
But if your opinions strong, do it under pseudonym, you can get a reputation for a fake name, not a problem. There is bunch of anonymous YouTubers with millions views and nobody knows their name or seen their face
