Also, most of the time, I understand better non-native speakers than native speakers. The hardest people to understand for me are native speaker with any accent that is not North American.
When I was younger, I was very self-conscious about my foreign accent. and I noticed that people who mentioned my accent in a negative way were systematically people from my own country whose accent was just as thick as mine (and probably were as insecure about it as I was). But mostly, I found native speakers to be very patient and polite with foreign accents, I'm grateful to them.
Eleven!!!
People with all kinds of accents, and with and without native English, have a hell of a hard time listening to what you're saying, because of your intent and the actual meaning of your words, not just how you pronounce them, which makes our ears bleed.
You sound like you have open sores and deep psychic wounds, so stop picking on them and people who speak differently than you do.
And cut it out with the intentionally cruel and spectacularly unoriginal body shaming too, buddy:
Also in general between both native and non native speakers, commenting negatively about someone's accent is considered rude, or colloquially, an "asshole move"
If you are a non-native speaker without encountering such accents you must be Indian, right ?
Also flagged? I'm seriously confused.
People usually can't change their accent. Complaining publicly about this is just rude, and on the verge of racism (speaking with someone with a French accent being "the more excruciating things I've experienced.").
Skill issue.
And how about cutting out the intentionally cruel and spectacularly unoriginal body shaming too, buddy:
Expect people to take offence if you complain about their accent — potentially very serious offence, as English accents and race or national identity are strongly linked in many places.
