I grew up in church but did not truly believe in Jesus. After going through a personal crisis, I had believed that I was a true believer and was an active church member for 15 years or so since my 20s. This has changed for me since the pandemic.
Since the pandemic (catalyzed by the George Floyd murder), I've stopped attending my Protestant non-denominational church. His murder helped me see what African-Americans have experienced repeatedly. I was devastated by the church's response. The white majority church (speaking for Southern Protestants, not necessarily for Catholics) refuses to have empathy for the plight of African-Americans.
The majority culture church (white evangelicalism) had a prominent role in perpetuating slavery, Jim Crow, etc. The confluence of white evangelicalism and the Republican party (overwhelming support for Trump) was the final straw for me.
