The denial of the general call is not the same thing as the denial of common grace/the free offer.

"Every man is obligated to repent and believe the Gospel, therefore every man should be called to repent and believe the Gospel."

is not the same as

"Every man is obligated to repent and believe the Gospel, therefore every man should be told that Christ died for them."

Please do not conflate the issues.
