There are a bunch of countries in the world with similar flags, almost identical. Ecuador, Colombia, and Venezuela for example. They all have the same flag. The only difference is the emblems. Honduras, Guatemala, and Nicaragua have the same case. What about Ireland and Italy? Very similar.
What Im trying to say is that it doesnt really matter. You pay tribute to your flag and you take it as your own cus it represents you. That other similar flag doesnt.
