Can justification be removed from embedded comments?

Question

I noticed that Blogger no longer includes my comment-form message with full-page and pop-up-window formats for comments. The message only appears with the embedded-comments format. And that format renders comments with full justification. (Why?)
Does anyone understand the Blogger template well enough to show how to make embedded comments appear with left justification only? To my eye, full justification looks ugly. And everything I read recommends against it for webpages. A sample comment with justification:

Thanks, Michael.
You can modify the code in your blog if you like, but generally we encourage people to use the Them Customizer, which you can invoke from the Theme page.
What you do is to paste this code into the Customizer at Advanced > CSS
.comments .comments-content .comment-content {
    text-align: left
}
You can just copy and paste. The only tricky part is the terrible user interface to the customizer, but of you poke around you should be able to navigate to that CSS option. The little grey triangles are the key.
To save changes, click on the floppy-disk icon at lower right on the page.
Let us know how that goes.

Michael, I agree with you typographical assessment of justified type. But these things are blog-theme specific, and you did not include a link to your blog.
Please do that and we'll try to see what can be done.
