Two-edged

It's a two-edged sword.

The little mermaid drank the burning, stinging draught, and it was like a sharp two-edged sword running through her tender frame.

Then there's that term 'gay'. Does that still mean all homosexual people? For some folks, as mentioned earlier, yes. For others, no. It is in reality a two-edged term. On the hand meaning all sisters and brothers, yet on the other hand sisters in the political, social, economic liberation movement, called Gay Liberation. It implies a political stand.
