As suggested by this answer, I would like to either delete the sailplane tag or merge it with glider. Can anyone make it ? (I don't have enough power/rights)

From the post you link
In particular, a glider is any aircraft designed primarily for unpowered flight. A sailplane, on the other hand, is a glider with conventional control surfaces.
I personally don't see how this can be interpreted to mean that glider and sailplane are synonyms.

1$\begingroup$ I also disagree with the proposed merge. Wikipedia considered and decided against a similar merge which im not saying we must follow, but is a useful data point. We also have a question right here on the difference - and being the answer was NOT that there is no difference, we should continue to distinguish the two. $\endgroup$– Jamiec ModSep 6, 2019 at 8:57
