Honest advice: Get a tshirt with "FUCK PUTIN" printed on it. Wear it everywhere, even if it's covered up by a jacket. If you find yourself in a risky situation, make sure it's showing.
Wearing it in Egypt? The OP knows better than us. It might simply be self-preservation. I won't fault him either way.
Choose your risk.
