Why are some reasons people are really against health care reform?

Please do not answer this question with vague answers or racist or ignorant answers that have nothing to do with what I asked.
I say this because I’ve seen similar questions posted that were simply filled with hate mongering answers but none that actually specifically listed actual changes and what they would mean.
I’ve read about what some of the changes would be but not exactly what they would mean for the public.
Please name One action of the bill reform that you object to an give a reasonable answer as to why it won’t work.
