You're absolutely right that some political parties wrongly use a term like "conservative" in their party name, or otherwise incorrectly portray themselves as being "right wing".
Ultimately, though, they're still left-wing parties in practice, pushing left-wing ideologies, regardless of the facade they might try to put up.
A party doesn't just become "right wing" because they claim to be, especially when their actions and policies are decidedly left-wing.
Left wing, due to the use of large and intrusive government, collectivism, government-run make-work projects, government-run infrastructure projects, central economic planning, conscription, a disregard for individualism, and other policies that are inherently incompatible with right-wing ideology.
