I'd just like to point out here that there are
legitimate points of contention by any
linguist,
anthropologist, or
minority group that the
English language and culture are embedded with subliminal
meanings.
In this case, we see the definition of a trench plow as a weapon of war. This word also exists as colloquialism to mean penis. Look at the shape of missiles and rockets. Not to mention that guns, the primary weapons of war, expel hot lead in explosive bursts.
Maybe these examples aren't enough to convince you. But the next time you begin to roll your eyes at a feminist, a civil rights advocate, or any other activist, think about all the other words in our language that convey this kind of message.
