Implicating against_window → on_glass
Link to implication

Reason:

All current and expected future against_window posts are on_glass. I would have suggested an alias but I can imagine some users might want to search for against_window specifically.

I suppose plexiglas windows would be almost indistinguishable from glass ones. +1

+ ½. Firstly invert the alias 'against_glass → on_glass', for the tag to match with others like 'against_wall' and 'against_tree'; and only then imply 'against_window' to it.

But lying or sitting upon a glass table is not leaning into, or "against," glass.

on table, on bed, and others also exist.

on_* is mostly used for horizontal surfaces, and against_* for vertical such as walls and trees. Glass can be either, and therefore doesn't solidly fit into either category.

But against_glass seems like the better fit, because most of the posts are of characters leaning against windows, shower stalls, etc. So plus one for reversing the alias.

Why not divide the tags then? Have one for horizontal glass, and have the other for vertical glass.

Since the overwhelming majority of 'on glass' cases are vertical, separating them seems quite unnecessary.
