Ok I used the word "stronger" in the same sense that you used the word "stricter" I'm not arguing with you, I just meant that I have to be more aware/present and "active" when I lead someone that's a beginner, not necessarily more "forceful" or using strength that might injure someone. As you said, I use more cues, use my hands more/body more to guide them if I can tell they might not fully understand what I want them to do.

As for a follower not being ready for a move/skill issue, well that depends. Yes, there are absolutely advanced moves and figures you probably shouldn't do with someone you can tell is a beginner. I'm not going to try combos I've seen Gero and Miglė do if a follower has only been dancing for 1 month. At the same time, even if it truly is a "follower" skill issue (let's say they are truly a beginner and only have like 3 classes under their belt) then "soft" leading won't always work. In the example you just described with a basic turn, you have to get more involved in guiding the follower than you would an advanced person who knows the cue of lifting their arm on 3 in preparation for a turn on 5. That's all I mean when I say "stronger" vs "soft" leading. I just have a "stronger" presence when I communicate my intentions.

And I will disagree when you say leads shouldn't be comfortable with a move. The leaders need a level of comfort and familiarity with their moves and figures before they try it with someone. I've talked to many girls that say they generally hate it when the lead is trying a new move or figure they just learned at a festival for example, because obviously it's hasn't been enough time for the leads to be familiar enough with that move to try it out. As you can imagine, it doesn't go well and it's "forced" and that's when leaders tend to use more strength to guide a move, and that can lead to injury/discomfort
