During her time as a Senior Royal, the Duchess of Sussex used the only social media she's allowed to have to make her political opinions known, but she did it subtly, knowing she was wading into dangerous waters with the Crown ... sources close to Meghan tell TMZ.
If you don't know ... Queen Elizabeth and her family are supposed to refrain from expressing political opinions publicly, but we're told Meghan felt it was important to get out messages reflecting her beliefs and values.
Our Meghan sources say she carefully crafted IG posts to avoid overtly saying what she was thinking or supporting, but the writing was on the wall ... or in the photos.
For example, when her friend and women's rights activist, Loujain al-Hathloul, was imprisoned in Saudi Arabia ... Markle knew she couldn't come out and condemn a foreign government.
Waiting for your permission to load the Instagram Media.
Instead, Meghan showed subtle solidarity by sharing a photo of herself with Loujain as part of a bigger post about One Young World ... a UK-based, not-for-profit organization supporting "global youth ambassadors."
That same post included a photo of Markle sitting next to Canadian Prime Minister Justin Trudeau, shortly after he won re-election -- a low-key shout-out of support for her friend.
Our sources say, for the most part, she knew how to walk up to the line without crossing it, which helped her dodge any issues with royal higher-ups. Call it effective self-censorship.
