You are generally correct.
Conservatives of the last century often weren’t economic liberals. Chesterton and his circle advocated semi-socialist policies, and of course we Catholics have Rerum Novarum and its later teachings. 19th century conservatives were even less libertarian. If you will recall, Bastiat’s most famous work is a response to Thiers, who supported high tariffs. Thiers was the man who crushed the Paris Commune.
All of which just goes to show that when you attempt to equate modern political position to those of the past you are constantly tripping over your own feet. At least if you are willing to recognize the realities of history instead of just projecting present-day concerns into the past.
