Exactly.
When the Reform movement says that it’s OK to eat Trayf and to marry a non-Jew,
and when the Conservative movement says that it’s OK to drive to Shul on Shabbos if the Shul is not within walking distance, and that it’s OK for a Kohayn to marry a divorcee,
there is no “V’ahavta L’reiacha Kamocha and things like Shivim Panim LaTorah.”
These are outright Torah violations, and speaking out against them is not Loshon Hora. It’s the violations that are being spoken against, not specific people violating them.
