(CNN)Meat-based idioms, like "flogging a dead horse" or "taking the bull by the horns," can be compared with homophobic and racist language, according to animal rights organization PETA.
PETA says phrases like 'bring home the bacon' are comparable to racism and homophobia
"Just as it became unacceptable to use racist, homophobic, or ableist language, phrases that trivialize cruelty to animals will vanish as more people begin to appreciate animals for who they are and start 'bringing home the bagels' instead of the bacon," PETA said on Twitter.
The group took to Twitter Tuesday, offering a graphic showing some possible alternatives to meat-related expressions.
Instead of "kill two birds with one stone" say "feed two birds with one scone," and instead of "being the guinea pig," say "be the test tube," PETA said.
"Words matter, and as our understanding of social justice evolves, our language evolves along with it," it added.
The comparison with racism and homophobia was met with anger on Twitter, with some arguing that PETA was trivializing race and gender issues.
