No I do not think modern/abstract art is created by those with no real artistic talent?
In fact your preferences ( To me if it doesn't look like what it represents or at leat look 'nice', then it isn't art! ) are also abstract because they are merely illusions in an abstract form, they are not the real thing, just illusions.
So you do like abstract art really and it seems like your thing is realism, where as I am a bit bored with realism as it is normal and mundane, repetitive, everywhere around me all the time. I am an entertainer, whose first priority is my own entertainment and if I find realism boring then I am not going to do it.
Don't get me wrong realism is the basic information that contributes to the creative process but to just mimic reality seems a bit boring, unnecessary even because it already exists, a bit pointless. There is always the desire to do something that has not been done, to explore that which is uncharted.
We all have real artistic talent so even those who use it badly in your eyes are not as bad as those who don't use it at all and all art is subjective anyway, we all like different things for different reasons.
No I do not think modern/abstract art is created by those with no real artistic talent, I think its quite the opposite and we all have a real artistic talent, that is often restrained by the illusion that realism, is something more than just another form of abstract art.
