Sure, this is the whole point of copyleft and it is a very good thing.
But copyleft has its drawbacks, especially when it comes to license
compatibility. This is why you should more seriously consider using an
existing copyleft license. License proliferation is not a good thing;
copyleft license proliferation is destructive.

It does claim the copyright by asking to apply the license to it.

No one can patent the grammar that you wrote, so this is completely
useless. The only point of these clauses seem to claim the copyright on
scripts using the language.
