Rather than going straight to meta by decrying downvoters, a better way to rescue unfairly (in your opinion) greyed out comments is: 1. upvote it yourself (which I'm sure you did) 2. reply to it engaging with its content. This could be simple agreement, or even better, acknowledgement of a good argument, good phrasing, or interesting/under-addressed perspective. Sometimes, the model of your engagement can speak more to how you think others should act than stating your opinion explicitly. At least that's where you should start. There be dragons in meta, don't invoke the dragons if there's still another way.
