I can't speak for Republicans since I'm not one, but YES to a certain degree Conservatives do "hate" a large number of those groups; for one simple reason.... they are unable or unwilling to take care of themselves, thereby forcing us (and society in general) to help take care of them.
Babies, schoolchildren, the elderly, unemployed, welfare, immigrants
Wait a minute
I was a baby once
I will be one day one of the elderly
I have been unemployed in the past and maybe again someday
Even though my parents helped my Grand mothers they were on welfare before they passed away
Most of us have immigrants in our family trees
Sounds like you are accusing Republicans of self hate?
