We need to produce under 280 characters. Need to count.
Let's count each part.

Count characters.
I'll count using approximate but need ensure <280.
Let's count using groups.
I'll copy and count manually.
I'll number each character.
But easier: estimate length. Likely under 200? Let's count.
I'll count each word plus spaces and symbols.
I'll write string and count.
Start:
W(1)e2a3r4 (space5) y6o7u8r9 (space10) c11o12l13o14r15s16 (space17) p18r19o20u21d22l23y24!25 (space26) 🌈 is one character? Emoji counts as one Unicode char. So after space, emoji char 27? Actually after space, we have 🌈. So let's treat as char 27. Then space after emoji? There is space after emoji before "The". So after emoji, space 28.
Now "The": T29 h30 e31 (space32)
"vertical": v33 e34 r35 t36 i37 c38 a39 l40 (space41)
"bisexual": b42 i43 s44 e45 x46 u47 a48 l49 (space50)
"flag?
