C++ is also a horrible thing. No-one should use it to create a user app. C/C++ are fine to make low-level things. SFML does low-level things by interfacing with the windowing system. When you create a high level application you should use a high-level language. There are several high-level languages with very good performances. There are even some that provide the same performances than C/C++. Programming with a high level language makes you write things more easily, quickly, and with less bugs. The result will be easier to maintain, contributors will contribute more easily with a higher level language.
C is ugly, yes that's true, C++ is not better, it is a very complicated programming language. A lot of people around even say often that this is one of the most complecated programming language.
Opinions, opinions there are many and everyone claims to have the truth
If you can't accept that people which are into C++ don't like to see C code then you'll have a hard time, not only on this forum, but in mostly all C++ related forums/IRCs/etc.
Also degrading C++ to a low level language makes me think about what your definition of a high level language is or if you've ever looked at low level languages. C++ is
a high level language and in my humble opinion
there's no reason the switch to another language just because your opinion is that C++ isn't good to work with.
Additionally the language you choose does rarely have something to do with the possibility for maintenance nor contributions, this depends way more on the code design and the public interest.
And I can only mark this again in bold: this is my opinion
Feel free to have your own, but getting newly on a forum and starting to call people trolls within the first few posts, just because he/she has a different opinion, doesn't really make a good look on yourself and it doesn't help to have a pleasant ambiance in here.
So please accept others opinion and if you want to discuss things do it without 'insulting' people you barely know.
