MAGA is the major counterculture at the moment (in the USA). It is different from others of the past (punk, hippies, the beats, racist, socialists, populists) but has the key markers such as rejecting the dominant paradigm, being big enough to write about but not big enough to be a movement, pulls largely from the dominant population group, has some but limited influence on the dominant culture, has its own “literature” and belief system, etc.

Note that what isn’t different is its dependence on telecommunications. I tried to think of legitimate countercultures before the late 1880s US populism but couldn’t. Regency fops didn’t count, nor did know-nothings.
