It's basic whataboutmeism
It was started as a form of dismissal. "Black lives matter" was responded to by saying, "No, all lives matter" in an attempt to shut down the BLM movement. This is no different to:
- Approaching a widower who's husband died and saying, "Why are you crying, everyone dies"
- Approaching a clinic for the families of suicide victims and saying, "What about the families of victims of homicide?"
- Approaching a support clinic for cancer patients and saying, "What about cardiac patients?"
Whataboutmeism
The Black Lives Matter movement starts you have 3 options:
1) Support it
2) Ignore it
3) Rally against it
All Lives Matter is very much the 3rd as it's in response to the BLM movement. If the All Lives Matter movement started before the BLM movement then there would be no issue here.
The ONLY reason people started saying all lives matter is because people were not given an option to Critique BLM as an organisation/movement. Literally everyone I've heard speak/write about BLM for the past few months have all agreed that:
- Floyd was killed by cops and they should be jailed for it
- Discrimination against anyone on the basis of their skin colour is wrong and should not be tolerated
But they also realised BLM was not an honest organisation. BLM was not and is not purely about black lives, it's also about tearing down the nuclear family, western democratic society and installing marxism in it's place.
If BLM was purely about civil rights for blacks and ensuring freedom and equality for all - then literally 99.9% of the world would support it.
But many people are aware of the language tricks being played by calling the organisation BLM.
People were sick of people told they weren't allowed to have an opinion and that any opinion they have (unless it blindly supports BLM) is racist.
So people came up with All lives matter which is the best possible ideal for any society to have.
