Cadet,
You can have your opinions: as many as you like.
When someone asks for them you can espouse them: in the meantime, if by shouting your mouth off you are going to screw over a whole bunch of your colleagues, don't expect to last long on line once they find out who you are.
I suggest that it would be prudent to take the advice of the others and keep your big gob shut, get behind the parapet and stay there!
Oh and stick your tree hugging idea of CRM right up your jacksy: when you have some good hours in the business you can have an a say, until then.....do as those wiser and more experienced souls tell you do. You may just survive your first few years by showing some humility.
