Christians have had centuries to articulate decent counterarguments to secular philosophies, and in that period of time their greatest accomplishment has been associating atheism with a type of unflattering headgear that stopped being relevant in 2004.
On the contrary. The charge of atheism has become so toxic that Bernie Sanders and AOC have felt the need to explicitly deny such charges.
One in four “non religious” Americans - a category I have voraciously attacked before - say they would be less likely to vote for someone who doesn’t believe in God.* “Decent counter arguments” are widespread, not the least of which is natural law, which an atheist by definition can’t believe in.
