There should be a thread dedicated to this subject. Liberals (progressives) want the "nanny state." Progressives feel they are mentally and morally superior to conservatives, therefore, they want to construct the laws and regulations according to their "standards"that everybody should obey.

Remember:

If a conservative doesn't believe in God--he keeps it to himself.
If a liberal doesn't believe in God--he wants it (God) eliminated.

If a conservative doesn't like meat--he don't eat it.
If a liberal doesn't eat meat, he wants to outlaw meat.

If a conservative does not like guns--he won't buy one.
If a liberal does not like guns, he wants to outlaw them.

These are just the tip if the proverbial iceberg of how liberals would change your world.
