Conservatism is inherently compassionate. Therefore we don't need any qualifiers.
Liberalism on the other hand needs to scream look at me look at me and the good thing that I am doing.
Conservatism concentrates more on the individual liberties and individual freedoms.
Liberalism focuses on the rights of a class over the rights of an individual usually by oppressing other classes.
The Constitution by nature, and the founding of our country, is designed to protect individual rights, not class rights.
Protecting one class over another vs protecting and promoting individual rights is communism.
