As Christians are wont to say, hate the sin, not the sinner.
Most Christians are good people (or at any rate not any different morally to the population at large), and adopting personal animosity towards this huge entire class of people is very unhealthy, but it’s perfectly alright to be angry at the Catholic Church as an institution if you feel some of its disgusting actions have failed you or your loved ones, or at the pernicious influence some denominations and churches exert on society and politics.
